ERS: Sustaining in Tough
Environments
In over 20 years of servicing – and understanding - the
mining industry, Tsebo Outsourcing Group’s Equality
Reef Services (ERS) places great emphasis on ensuring
that meals are designed to sustain some of the most
hardworking people in the country.
“In dealing with so many people in South Africa who are
immuno-compromised, ERS re-engineered all its menus
to proactively address nutritional intake, with particular
attention to those who are HIV Positive,” St Clair-Laing
says.
“Intense physical labour means the body has to perform at
peak for long periods of time, and this requires food that
provides energy while building muscle and replenishing
vital vitamins and minerals that may be depleted under
strenuous physical conditions and heat,” says Andrew
St Clair-Laing, MD of ERS. “In providing our services to
our clients, our first priority is to determine the nutritional
needs of their staff members.”
“With the mines implementing programs to assist workers
who are HIV positive, we felt that HIV wellness should
not only encompass medication, but must incorporate a
growing emphasis on good nutrition that complements
and reinforces the effect of medicines.”
Besides a well balanced meal that caters to the basic
needs of all workers, ERS takes into account the energy
expended by manual labour and accommodates with
energy-giving carbohydrates and muscle-building proteins.
For example, a key ERS offering in the mining sector is
the Phambili Miner Diner, which supplies catering for
mine hostels and focuses on a range of nutritious, filling
meals.
“In conjunction with our Executive Chefs, Dieticians and
Operations Managers, ERS has created menus that offer
the customer a broad range of freshly prepared products
which are individually priced to suit most budgets and
customer preferences. Price - while an important ‘bread
and butter’ issue to ERS - must be balanced with proper
nutritional value.”
A key area of focus for ERS is meeting the nutritional needs
of workers whose immune systems can be compromised
by illnesses such as tuberculosis and HIV.
As a technology driven and innovative company - even in
a market that is not highly sophisticated - ERS prides itself
on its developments and innovations. These include the
smart card, which offers benefits like efficient management
and safety for employees, as they do not need to carry
cash. The payment for meals is linked to a Point of Sale
(POS) system that is supported by a smart card with a 1kb
chip capable of storing customer information.
While Equality Reef Services’ core business is catering,
this division of the Tsebo Outsourcing Group offers a
variety of services that make the company a hospitality
service specialist rather than purely a caterer. ERS is well
qualified and experienced in entertainment, shops, hostel
registration, residence management, purchasing and
estate management.
“Often several of our services form a vital part of our
clients’ operations, but we maintain a focus on healthy
meals, healthy miners and a healthy bottom line for our
clients,” St Clair-Laing concludes.

The issue of Acid Mine Drainage (AMD) has captured the headlines in South
Africa recently with the Department of Water and Environmental Affairs stating
that in 17 months acid water will start decanting - from the central basin, under
the City of Johannesburg- and contaminating groundwater. To prevent this, a
new pumping station and upgrades to a high-density sludge treatment works are
urgently required. The environmental implications are grim to say the least but
there is some hope if action is swift to counter the threat.
In this issue we look at the eMalahleni Water Reclamation Plant which is one of
only two such initiatives in South Africa, and the only one to treat water from as
wide an area as the Witbank basin, a project like the eMalahleni Water Reclamation
Plant is a rarity globally. Yet as water continues to become an ever more precious
commodity, plants such as this are likely to become more common.
With the decantation of acid mine water currently threatening the Witwatersrand,
eMalahleni it is an obvious pointer as to the direction that the government should
look towards for a solution.
For the rest of Africa with its nascent mining industry this should be a warning of
the legacy that abandoned mines leave behind for future generations .

Investors Eye Mining Potential in Guinea
Guinea
Investor interest in Guinea's mining potential is facing a renewed revival as
global demand for iron ore starts to pick up, but this investor confidence may
face a setback as talk of mining reviews looms.
In spite of these setbacks, investor interest has not been dampened, as seen
by recent activity in the past few weeks. Several large mining contracts have
been signed by mining companies and investment funds for the exploitation
of Guinea's mineral wealth; even though an agreement was in place that

regime while there is a sovereign risk crisis in Europe.
Ahead of a federal election coming August in which the government's new

Lead Poisoning - MAN Cautions against Illegal
Mining
He said: "Most minerals contain one level of impurity or the other. Some of these
impurities are radio-active in nature. Some of them release poisonous gases that
are not visible.
The Miners Association of Nigeria, MAN, has cautioned against illegal
mining, saying the lead poisoning in Zamfara that reportedly killed 163
persons, was regrettable. The MAN National President, Sani Shehu,
said that the incident, which occurred in Anka and Bukkuyum Local
Government Areas of Zamfara was "purely a result of illegal mining."
Shehu explained that mining was a rule-governed profession, saying: "If you want to
be a miner, there are rules and regulations that must be obeyed."
He said the association and the Federal Government were collaborating to ensure
the artisanal miners were formed into cooperatives, adding that the collaboration
was yielding results.
Changes for Local Coal Mines
As proposed by Representative George Miller, chairman of the House
Education and Labor Committee, the package imposes stiffer criminal and
civil penalties for certain mine safety violations. The Mine Safety and Health
Administration, which has been under fire for perceived lax oversight, will be
given more authority to close mines with a record of safety violations and will
have broad subpoena powers in accident investigations.
The U.S. House of Representatives is contemplating tougher regulations on
underground coal mines to improve safety in what remains one of the nation's
most dangerous industries. It is a move that could hold consequences for
major mining operations in Southwestern Indiana.
Bruce Watzman, senior vice president of the National Mining Association, said
U.S. mining operations have reduced job fatalities by 72 percent and nonfatal
injuries by 64 percent over the past 20 years.
South Africa Unveils its New Mining Charter
South Africa has intensified its drive to Black Economic
Empowerment (BEE) with the unveiling of a new mining
charter. The government, led by President Jacob Zuma,
announced the new charter, following the country’s
failure to attain the target of 15 percent empowerment
of business by 2009 under the previous charter.
"The 15 percent target for 2009 was missed and there
is now an opportunity for the industry to make up for
that," Mineral Resources Minister, Susan Shabangu
said in a speech in Pretoria. Minister Shabangu led a
cast of the industry’s stakeholders in signing the mining
industry strategy for sustainable growth and meaningful
transformation.
The agreement was signed by the Minister, as well as
the National Union of Mineworkers (NUM) President
Senzeni Zokwana.

The Chamber of Mines, a consortium of mining companies in Zambia has

to finance infrastructure projects like roads damaged by mining activities,
highly placed sources that preferred anonymity said all taxpayers including
the mines contribute to the central treasury.
The sources said that government was independent enough to supplement
taxes through borrowing to finance public projects such as roads and other
infrastructure. The sources advised people to bear in mind that the mines

paid taxes that go into the national treasury. “We are not in a position to
know the distribution of resources from the national treasury and government
is independent enough to decide on how to supplement taxes through
borrowing to finance public projects such as roads and other infrastructure,”
said the sources.
“False impression has been created that mines do not pay taxes but money
is paid into the national treasury including VAT (Value Added Tax), increased
PAYE (Pay as You Earn), import and customs duty and several domestic
taxes including council rates.”

Mr. Bruce Shapiro
African Mining Brief embarked
on an interview with Mr. Bruce
Shapiro of the Canada-South
Africa Chamber of Business.
Bruce Shapiro was born in 1943 in Johannesburg
South Africa and immigrated to Toronto, Canada
in 1977. He obtained his Bachelors in Commerce
(part time) at the University of the Witwatersrand,
while working for the OK Bazaars (1929) Ltd,
the largest retail organisation in South Africa at
the time and the largest in Africa. On obtaining
his bachelor’s degree in 1966, OK Bazaars
sponsored Mr. Shapiro to do a Masters of Business
Administration full time at the University of Cape
Town Graduate School Of Business. “I was the
first person in South Africa to be sponsored for
an MBA by a commercial organisation” Shapiro
added. He graduated in 1968.Having not gotten
any formal training in the mining industry, Mr
Shapiro believes that the principles of business
are valid no matter what industry one is in and as
he is only involved in the attraction of finance, the
promotion of destinations and the promotion of
certain projects, Shapiro does not need to have
any technical knowledge.
He is a member of the Canadian Institute of
Mining (CIM) and the Prospectors and Developers
Association of Canada (PDAC). Prior to becoming
involved in mining in 2000 when he became
Chairman of the Canada-South Africa Chamber
of Business, Shapiro had been involved in retail,
real estate, plastics, finance and teaching finance,
accounting and retail in South Africa and Canada.
He at one time was the head of the Finance
department for the Damelin Management Institute,
the largest educational institution of its kind in
South Africa, and a director for the post graduate
diploma in International Marketing and Marketing
Management at one of the top Canadian degree
granting colleges.
“My teaching activities were always part time only
as I enjoyed the interaction with enquiring minds
and it kept me current in areas important to my
activities. In short there are few areas of business
that I have not had something to do with over
my career that has so far lasted a little under 50
years!” added Shapiro. On why he left the Business
industry for the Mining industry, Shapiro had this
July - August, 2010
to say: I felt that to become relevant we needed to
cater to and build upon existing strengths between
the two countries while bringing new areas, such
as tourism, infrastructure and agriculture on more
slowly.
About Canada-South Africa Chamber
of Business
In 2000 he joined the Canada-South Africa
Chamber of Business to assist in developing trade
with, and investment into, South Africa. Shortly
after, Shapiro was elected chairman. Shapiro
approached the chamber as a business that
sought to make itself sustaining. His review of
the historical bilateral trade between Canada
and South Africa both before and since the lifting
of sanctions in 1994 indicated that most of the
business between the two countries was in the
mining area and so he set about attracting some
of the more significant players like De Beers
Canada who became the catalyst for other mining
companies to join.
The Chamber now has over thirty mining
companies involved in its activities. Canada is the
head quarter of about 57 percent of the world’s
listed mining companies as a result of the powerful
mining stock exchange there. The Chamber does
not participate in any mining ventures it encourages
investors to invest in the ventures. The Chamber
benefits both countries by helping promote the
destination as an attractive investment opportunity
and by raising the issues that detract from
investment such as nationalisation, corruption,
security etc. Investment brings jobs to South Africa
and by using Canadian expertise Canada benefits
too. On venturing to other countries, the chamber
recognises that its members have interests in other
parts of Africa and is in the process of changing its
name to the Canada-Southern Africa Chamber of
Business and to promote other African countries
as good mining investment destinations.
Challenges in the Industry
The holder of the South African Consul General’s
Entrepreneurial award says he has experienced
Mr. Bruce Shapiro
some challenges in the mining industry, especially
in the recent past. The chamber is heavily skewed
to mining and infrastructure related to mining; the
uncertainties such as commodity prices, world
economy, security, governance in various African
countries, power supply and calls for nationalisation
in South Africa and (and other jurisdictions) are a
challenge. By holding seminars and events where
open discussion of various issues takes place and
people directly involved can talk to each other on
a personal basis the chamber confronts these
issues. The Chamber continues to provide toplevel networking and events, which have helped
it grow their membership each year. Mr. Shapiro
says that currently they are the dominant African
focused organisation in Canada concentrating on
the private sector.
Mr. Shapiro believes very strongly that if Africa
is to become the powerful continent is should
be, mining is the only realistic industry to get
things going. Transparency and sustainable
development with government cooperation and
community involvement (leading to a social
license to operate) is the way to go.
A welcoming and stable environment will attract
capital. Dealing with countries like Canada which
has a serious commitment to Corporate Social
Responsibility and the capital markets and all of
the skills to assist in the development of mines
will benefit African countries in the long run.
Unfortunately the current economic state is badly
to say the least affecting this industry.
Certain commodities have not been really affected
but the uncertainty in the global economy is
restricting investment everywhere. Banks and
shareholders are nervous and only what are
perceived to be the “best” investment opportunities
in the safest countries will attract the needed
investment.
Mr. Shapiro takes time out for photography,
cooking, reading as well as theatre.

Here lies the potential to capitalise on improving
energy efficiency and at the same time reduce
carbon output and energy costs by increasing
the efficiency of pumps used during a mining
activity. So how do we increase the efficiency
of pumps? This article by African Mining Brief
touches on methods that are making a significant
contribution.
Pump systems are at the heart of production
in mines. They are also the largest single
user of electricity in industrial and commercial
applications, consuming at least 1100 TWh
or 15 percent of electricity world-wide.
Unfortunately, these important components
often operate at poor efficiency levels –
anywhere between 15 percent and 40percent
inefficiency.
Electricity wasted in the pumping process
is often hidden or viewed as inevitable and
unavoidable but in fact the average pump
application could improve efficiency by
between 20 percent and 40 percent. This
situation is worsened by the global shortage of
qualified engineers meaning there are fewer
people able to implement essential energy
reducing measures. According to progressive
lifecycle cost models, electricity use during
the lifetime of a pump accounts for up to 90
percent of the ownership cost, which means
that increasing your pumps efficiency could
result in considerable cost savings.
South Africa is already experiencing an
electricity supply shortage so is Kenya and
Zimbabwe. Due to the large volumes of power
they require, pumps are a prime target for
increased energy efficiency in an attempt to
contain industrial electricity demand. Some of
the pump systems used in the mining industry
includes:
Water Supply
Most often well pumps which supply the mine
with their primary source of water.
Process Pumps
Pumps that move solutions throughout the
mining processes such as raffinate, Pregnant
Leach Solution (PLS), thickener, acid water,
cooling water, organic solvent, electrolyte and
dump Leach.
July - August, 2010
Electricity wasted in the pumping process is often hidden
or viewed as inevitable and unavoidable
Tailings Pumps
Post-processed solution is collected in tailings
ponds to allow the solid particles to settle
out. This liquid is then usually pumped to a
treatment facility and recycled back into the
process.
In designing a pumping system, pump
efficiency should achieve a certain amount
of energy savings. However, system pumps
are only one element that will determine the
overall efficiency of that system. Additional
components and elements of importance are:
• The boiler, chiller or heat exchanger
• Piping size and design (to reduce
losses)
• Valve losses
• Radiation efficiency
• Water temperature in a heating
system (which should vary with outside
temperature to reduce heating/cooling
costs)
• Motor efficiency, pump size and use
of variable speed controls to match the
system load conditions
• Operating point
• Controls to monitor and operate the
system to match the load changes
(www.instrumentation.co.za)
Post-processed solution is collected in tailings ponds to
allow the solid particles to settle out.
In designing a pumping system, pump efficiency should
achieve a certain amount of energy savings.
Friction Devices
In a piping system, a pump's energy is
consumed by the friction of the piping and
fittings, heat exchangers, heating/cooling
coils, control valves, balance valves (manual
and automatic) and the use of constant speed
pumps. Eliminating all the friction wasting
devices in a system can reduce the pump size
and energy usage.

Staffing
The school competes for human resource with the mines. This has given
the school great challenges as retaining and attracting staff from the mines
is extremely difficult. Zimbabwe School of Mines has put up strategies to
retain staff within the school; the Staff Retention Program was approved in
2007 and is still ongoing .With the stabilisation of the economy the school
expects to achieve greater results with its staff retention program in 2010
and beyond.

ZSM - Small Scale Miners
The institution has had a long standing relationship with small scale miners
as these are mostly owned by past ZSM students. Their workers are also
enrolling for courses at the school. In terms of Corporate Governance
issues the ZSM has offered tremendous support over the years as well as
presentation of relevant papers, practical demonstrations to the Zimbabwe
Miners Federation and Women in Mining. The two organisations are at
liberty to enroll and join mainstream courses and do modules of their choice.
Content mainly focus on proper mining methods, environmental rehabilitation
systems and safety.
Diamond and Methane Gas Discoveries
A coal-bed methane project course is on the cards which will assist in the
provision of trained personnel in the exploitation of methane gas at Lupane.
The Distance Learning approach is being broadened to meet the new
dynamics in the mining Industry. The discovery of diamonds in the country is
a great challenge and opportunity to the school. It has put up plans to ensure
The school is providing about 30 percent skilled manpower
for the mining industry.
the curriculum is revised to cater for the geology and metallurgy of diamonds
and methane gas by 2011.
The institution will soon seal international partnerships deals with specialised
School of Mines like the University of Zambia and the Camborne School of
Mines of United Kingdom. ZSM also envisages itself offering a Masters in
Mineral Sciences by 2015 with assistance from these international colleges.
Employment Prospects and Contributions to the
Economy
The school is providing about 30 percent skilled manpower for the mining
industry. Mining houses such as Mimosa Mining Company, Metallon Gold,
Zimplats, Hwange Colliery, and ZIMASCO have absorbed most graduates
from the school. The ZSM technician is found all over the world and quite
a number of mine managers in Zimbabwe passed through the Zimbabwe
School of Mines.
Some senior government officials hold ZSM diplomas in Zimbabwe and as
far as Canada. The Zimbabwe School of Mines has contributed immensely
to the economy of Zimbabwe by providing skilled manpower which is needed
in the industry. With brain drain affecting the Zimbabwean economy, the
institution has managed to provide manpower for the mining industry, hence
its 2010 planning theme, “skills provision in readiness for the recovery of the
mining industry”.
Facilities
ZSM boasts of state-of-the-art fully equipped laboratories, lecture rooms and
a 300 seater auditorium. On-site hostel accommodation for student is also
provided as well as canteen facilities for both students and staff.

The November 2004 announcement that Brazilian
mining company Vale had won the bid to develop
a coal mine at Moatize, in Mozambique’s Tete
Province, was a major landmark in the country’s
economic recovery. Several governmentsponsored ‘mega projects’ had already been
implemented and the GDP was on the upturn,
but the trickle-down effect of these projects made
little real difference in the traditional and informal
sectors.
The Moatize Coal Project, the fourth such
mega project, was consequently given a strong
developmental mandate: to act as a catalyst for
development in the Zambezi Valley in order to
improve local socio-economic conditions and
productivity.
In its development proposal, Vale – the secondlargest mining company and the largest producer of
iron ore worldwide – showed a strong commitment
to community and social development. Included
in the company’s long-term strategy was the
development of a mine with a capacity of 11
million tpa – of which the current project is the first
phase.
Of all the challenges involved in setting
up a plant of this magnitude in a
largely undeveloped country, logistics
ranks amongst the most taxing.
24
A Gargantuan Investment
Already the project has brought international
visibility to Mozambique’s potential as a coal
producer, spurring investment by other large
international companies in the Tete region of the
Zambezi Valley.
The first phase of the Moatize mine plant, which is
currently under construction, will have a capacity
of 11 million tonnes per annum: 8.5 million tonnes
of metallurgical coal (for steel production) and
2.5 million tonnes of thermal coal (for electricity
generation), which will be exported to Brazil,
Europe, Asia and the Middle East.
ABB’s Electrification and Control
System
In 2009 Vale awarded a contract to ABB, an
international power and automation technology
group, for the electrification and automation of the
Moatize coal mine. ABB collaborated internally
with members of the Centre of Excellence for
Mineral Processing in Switzerland, and formed
an external consortium with B&W Electrical
and Instrumentation – one of the largest E andI
contractors in Southern Africa – who is responsible
for equipment installation.
According to Mehrzad Ashnagaran at ABB in
Switzerland, ABB’s scope of works at Moatize
includes:
•
Extending the existing substation at
Matambo with a new 220/66 kV bay including
a 40 MVA 220/66 kV transformer and
extension to the existing double busbar
system.
• Installing a 44km-long, 66 kV overhead line
from the Matambo substation to the Moatize
site.
July - August, 2010
• Building a new switchyard equipped with
SCADA system at the proposed Moatize site
with a 40 MVA 66/22 kV transformer.
• 22kV GIS switchgear and DC power supply
units, plus 22kV power factor and harmonic
filter system.
• Control system equipment, complete
with workstations and furniture. DCS
equipment and software packages.
• Plant lightning and earthing protection
system. Plant lighting and small power
system within substation area.
“The order contains conceptual and detailed
engineering, manufacturing, erection supervision,
commissioning, training and design schedule,”
explains Mehrzad Ashnagaran. “All specified
equipment is compatible with the site’s climatic
conditions (altitude, temperature and seismic
requirements) and is type tested and certified.”
Design Highlights
Various types of VVVF drives have been installed
on the project, and variable speed drives smaller
than 75kW are built in MCCs. “By providing the
Multi Drive solution in variable speed drives in this
project, ABB has optimised the sizes of the prefabricated E-rooms, resulting in a more economic
solution and reducing the costs for the project,”
explains Mehrzad Ashnagaran.
Except in the case of the main substation, airconditioned, portable, pre-fabricated electrical
rooms have been provided for all other
substations. In addition, compact and movable
substations called “Minisubs” have been designed
for a part of the 22kV distribution in the plant.
These are built on steel baseframes with a
July - August, 2010
distribution transformer up to 1600 kVA and an
LV distribution board. “Ring main units (RMUs)
are widely used in the distribution system,” adds
Mehrzad Ashnagaran. “Each RMU is a SF6
insulated compact switchgear with short circuit
current of 25 kA.” “We are proud to have been
able to provide the most comprehensive service
and repair portfolio amongst all major electrical
vendors in Southern Africa,” concludes Mehrzad
Ashnagaran. Veli-Matti Reinikkala, head of ABB’s
process automation, concurs. “ABB’s vast industry
experience, combined with our comprehensive
automation and power offerings, provide our
customers with the robust solutions they need for
these large scope projects.
Our ability to provide a complete scope of supply,
global expertise and excellent local resources
helped us to win this order.”
Challenges
Of all the challenges involved in setting up a
plant of this magnitude in a largely undeveloped
country, logistics ranks amongst the most taxing.
The port of Beira, 575km from Moatize, is intended
to handle all phase one exports, and the existing
Sena/Beira railroad is currently being upgraded to
cope with the anticipated initial export loads.
Notwithstanding the challenges, Vale is optimistic
that solutions will be found to the project’s
numerous challenges, both current and anticipated.
The Moatize project is under implementation and
is expected to be concluded in the first half of
2011. ABB’s portion of the work is expected to be
completed by the end of 2010.

The eMalahleni Water Reclamation Plant
A flagship water reclamation plant at eMalahleni in South Africa’s Mpumalanga
Province is turning mine waste into a municipal treasure. Elaine Young discusses
how the project addresses what was once a cruel irony: too much water in
eMalahleni’s mines, and too little for its residents to drink.
Home to twenty two collieries within a 40km
radius, Emalahleni – the “place of coal” formerly
known as Witbank – lies 150km north-east of
Johannesburg. Rapid industrial, commercial and
residential growth in the last twenty-five years
overstretched the town’s water supply, resulting in
too much water being taken from Witbank Dam by
the mid 2000s.
At the same time, Anglo American Thermal Coal
was battling with the opposite problem. A body of
water larger than Witbank Dam itself, covering
thousands of hectares and growing in volume by
over 20 megalitres per day, was situated above
the coal deposit it was trying to mine. Until then,
the company had been cleaning its waste water
enough to legally discharge it into the nearby
Olifants River.
A decade of research into better treatment
methods led to a major coup in 2007. Using
reverse osmosis, polluted mine water was cleaned
to potable quality, producing less than 1 percent
liquid (brine) waste – a water recovery method of
more than 99 percent. Using external pressure,
reverse osmosis filters dissolve particles as small
as 0.1 nanometer across a selective membrane.
“Anglo American Thermal Coal decided to treat the
water further and supply it to the local municipality
where a supply shortage had been identified,” says
26
Peter Günther, Regional Manager - Hydrology at
what came to be known as the eMalahleni Water
Reclamation Plant. “At present we supply nearly
80 percent of our purified mine water directly to
the municipal reservoir”, adds Günther.
Anglo American Thermal Coal and BHP Billiton
Energy Coal South Africa (BECSA) partner in
the R300 million(US$41 million) joint initiative,
a public-private partnership with the eMalahleni
Local Municipality. BECSA provides 15 percent
of the water input from its defunct South Witbank
Mine, while Anglo American Thermal Coal
supplies the balance from its Landau, Greenside
and Kleinkopje collieries.
plant is bottled and profitably marketed under the
4Life label by the White River Beverage Company,
a venture of Anglo American’s development and
empowerment arm, Anglo Zimele.
Phase Two to Double Output
Development of a second phase is due to begin in
the second quarter of 2011, for commissioning in
late 2012. Once complete, this phase will increase
the plant’s processing capacity to 50 megalitres
per day. Of this, treatment for five megalitres will
be made available to other mining houses in the
area, broadening the facility’s catchment area and
industry buy-in, making it a truly regional water
reclamation scheme.
The plant was commissioned in 2007 and
currently desalinates mine water to potable quality
at a rate of 25 megalitres per day. Of this, up to
20 megalitres per day are pumped directly into
the municipality’s reservoirs, meeting some 20
percent of its daily water requirements.
The balance is piped to Anglo American Thermal
Coal’s Greenside, Kleinkopje and Landau
collieries, as well as various nearby Anglo
American Thermal Coal service departments, for
domestic use and for mining activities, such as
coal processing and dust suppression. In addition,
a small percentage of the water produced at the

Staff houses constructed using gypsum-based building materials
The plant will also supply up to eight megalitres
of industrial and potable water per day to
Zondagsfontein, an Anglo Inyosi Coal greenfield
project, to BECSA’s Klipspruit mine, and to the
Phola coal washing plant, a joint venture between
the two mining houses.
Venn-Milford Incorporated, a project service
company, has assisted Anglo American Thermal
Coal throughout the entire life cycle of the project,
from concept to close-out.
Integral to the on-time and on-budget completion
of each section of the project so far has been
the company’s role in estimating during the
prefeasibility and feasibility stages, procuring the
various construction packages, administering the
contracts, monitoring the project schedule, careful
cost control and contractors’ final accounts.
According to company Director Quintin Rooza,
“The biggest challenge from Venn-Milford’s
perspective was to ensure that the project was
completed within its budget.
At the end of the day we are proud to say that
the project was commissioned within the allocated
approved budget. Overall we think the biggest
triumph of this project was that a liability was
converted successfully into an asset, not only for
Anglo American Thermal Coal but also for the City
of eMalahleni.”
Striving for Sustainability
Apart from solving a serious municipal water
shortage and preventing polluted mine water
from decanting into the local river system, the
custodians of the project are making sure it
remains sustainable well into the future.
The plant design takes into account the remaining
20-25 year life of contributing mines, and also
caters for the post-closure desalination of more
than 30 megalitres of mine water per day.
An ongoing sustainability challenge is to become
a ‘zero waste’ facility through the 100 percent
utilisation of the plant’s only significant by-product,
gypsum.
Anglo American Thermal Coal is currently involved
in two research projects, one investigating
the conversion of waste gypsum into sulphur,
limestone and magnesite, and one focusing on
the production of usable gypsum-based mining
and building products (whose sale may offset the
cost of the water treatment facility to make it truly
sustainable in the long term.)
As water continues to become an ever more
precious commodity, plants such as this are
likely to become more common
July - August, 2010
So far, the company has successfully built thirty
out of sixty four planned houses using gypsumbased building materials, not only proving the
viability of the solution but creating affordable
housing for its own employees. (The latter is a
provision of the Sustainable Housing Charter, a
subsection of the Mining Charter, which aims to
replace mine accommodation with affordable
housing owned by mine employees themselves.)
Venn-Milford are similarly committed to long-term
sustainability and are currently assisting Anglo
American Thermal Coal in further feasibility
studies for potential expansion of the existing
Emalahleni Water Reclamation Plant to treat mine
water from other sources.
Another collaboration with Anglo American
Thermal Coal involves the promotion of the on-site
treatment of mine water using modular treatment
plants which can be relatively quickly deployed
and commissioned at some of the company’s
other mining operations.
One of only two such initiatives in South Africa,
and the only one to treat water from as wide
an area as the Witbank basin, a project like the
eMalahleni Water Reclamation Plant is a rarity
globally. Yet as water continues to become an
ever more precious commodity, plants such as
this are likely to become more common.
With the decantation of acid mine water currently
threatening the Witwatersrand, it is significant
that the Western Utilities Corporation in South
Africa recently concluded a feasibility study on the
possibility of a similar solution for the gold mining
industry.
Considering the manifold benefits, let us hope
there is the buy-in needed to make a real
difference.

Massive Tailings Recovery Plant
for First Uranium
In line with its mission to become a significant low-cost producer of uranium
and gold internationally, First Uranium is making its mark in tailings recovery in
South Africa’s North West Province. Elaine Young takes a look at progress on
the corporation’s landmark initiative, the Mine Waste Solutions Tailings Recovery
Project.
Currently the largest of its kind in the world, the
Mine Waste Solutions (MWS) Tailings Recovery
Plant is located near the town of Stilfontein,
approximately 160km from Johannesburg. In
total, the MWS operation spans fourteen tailings
deposits from three old gold and uranium mines,
and covers an area stretching approximately
13.5km north-south and 14km east-west.
Together, the dams represent in excess of 325
million tonnes of mineable mineral reserves,
yielding an estimated 54 million pounds of uranium
and 2.9 million ounces of gold. Reclaiming gold
and uranium from the dams is a hydraulic process
which entails slurrying the tailings with highpressure water jets, then pumping them to a plant
for mineral recovery.
30
Phased Implementation
Shortly after First Uranium listed in December
2006, it was able to fast track initial plans for
the Buffelsfontein tailings recovery project by
acquiring the MWS gold extraction plant in June
2007. Following the acquisition, a pipeline was
built from the Buffelsfontein tailings dams to the
newly acquired gold plant, with delivery of tailings
commencing in December 2007.
The plant began operating at its planned throughput
rate of 630,000 tpm in July 2008. In April 2008,
construction of a second gold plant and the first
two modules of a uranium plant commenced about
500m from the first gold plant. Known as Phase
1B, the project was commissioned in two stages.
The gold circuit was commissioned in August
2009 and the uranium flotation plant is in the final
stages of completion ahead of commissioning.
With a footprint 1.1km long and 900m wide,
the US$ 200 million project was completed
by the EPCM contractors, MDM Engineering.
Overlapping with the completion of Phase 1B was
the commencement of Phase 2 – a US$125 million
contract for the construction of a third gold circuit
and associated uranium module. This is due for
completion in the second quarter of 2011.
Project Design
MDM Engineering was awarded the EPCM
contract for both Phase 1B and Phase 2 of the
MWS Tailings Recovery project. According to
George Bennett, Executive Director at MDM
July - August, 2010
Engineering, once the uranium circuit for Phase
1B has been commissioned, the existing process
flow (Reclaim – CIL – Tailings) will change to a
process of reclaim, flotation, CIL (carbon in leach),
leaching, CCD (counter current decantation),
IX (ion exchange), SX (solvent extraction) and
precipitation. The commodities yielded upon
completion of Phase 1B will be gold and uranium,
with gold currently being produced.
The MWS project currently processes tailings at a
rate of 1.2m tpm, of which Phase 1B contributes
650,000tpm. It will ultimately reach a final
throughput rate of 1.9m tpm upon the completion
of Phase 2, which will add another 650,000 tpm of
modular capacity.
At this point the material being treated will arrive
at the flotation circuit at a rate of 1.9m tpm. The
flotation circuit is designed to float uranium by
concentrating the large delivered stream of 1.9m
tpm into a smaller concentrate for subsequent
processing in the uranium plant, which has a
capacity of 135,000 tpm.
Andre van Wyk, General Manager of Process
Engineering at MDM, explains the recovery
process as follows: “Tailings are reclaimed from
the slimes dam using water jets. The reclaimed
tailings are screened to remove vegetation before
they are pumped to the flotation plant 13km
away.
The tailings go through a flotation circuit from
where the flotation concentrate goes to the uranium
plant. “In the uranium plant the concentrate is
leached in sulphuric acid to remove the uranium.
The uranium solution is separated from the solids
in the pulp in the CCD circuit.
The solids stream goes back to the thickener
where it is joined by the flotation tailings before
being pumped to the CIL plant for the recovery of
gold.
After gold recovery, the plant tailings are pumped
to a new tailings facility. “The uranium-carrying
solution is treated in an Ion Exchange (IX) plant
and Solvent Extraction (SX) plant to remove
impurities before the uranium is precipitated as
ammonium diuranate (ADU), which is then sold to
the market.”
Difficult Conditions
For George Bennett, the successful implementation
of the Phase 1B and Phase 2 projects has been a
hard won victory.
Troubled by labour unrest and strike action, the
project also had to contend with the unexpected
withdrawal of Environmental Authorisation for a
new project, its planned new tailings storage facility
(TSF) – as a result of which work on Phase 2 of
the MWS project was temporarily suspended.
Numerous changes to the original (Phase 1B)
design also had to be made.
Benefits
Apart from the obvious economic benefits of
“recycling” valuable commodities such as gold
and uranium (and providing a significant amount
of employment), Bennett cites environmental
advantages as a major spin-off of the tailings
treatment process.
The tailings remaining after the treatment process
are significantly more benign after the removal
of gold, uranium, pyrite and sulphur during reprocessing of these tailings. (The new TSF,
intended for commissioning by May 2011, will
build on these environmental benefits, adding
the advantage of reduced erosion on side slopes,
water recycling systems and better tailings
retention through positioning on impermeable
subsoils.) “We are very proud of what we have
achieved at MWS so far,” concludes Bennett. “It
is a massive plant, built under difficult conditions.”
Roll on the successful completion of Phase 2.

Modikwa Platinum Mine
Puts People First
In the last issue of African Mining Brief we ran a
feature on Modikwa Platinum Mine, a 50:50 joint
venture between Anglo Platinum and African
Rainbow Minerals.
The mine is situated on the Eastern Limb of the
Bushveld Igneous Complex in South Africa,
and produces approximately 300,000 ounces of
platinum group metals annually, of which 135,000
ounces are platinum concentrate.
Upping the ante even further requires a
whole-system approach which combines
interventions into ‘soft’ systems such as
procedures, communication and
relationships with ‘hard’ systems
approaches such as safer blasting
34
In this issue we take a closer look at two interrelated
aspects of the mine’s culture – its safety obsession
and its social upliftment initiatives – which serve
as a valuable model for an industry often much
maligned for its poor performance in these areas.
On the 2nd of December 2009 Modikwa Platinum
Mine achieved the safety milestone of 6 million
fatality-free shifts – and anticipates reaching 7
million in September 2010.
With over fifty consecutive fatality-free months
currently under their belt, management at Modikwa
is however far from complacent about safety on
the mine. Nine miners died between 2002 and
2006 – a number management regards as “nine
too many” – and standards and procedures
are constantly being revised to prevent any reoccurrences.
“Even though we have achieved phenomenal
performance, especially with what we regard
as the ‘six killers’, our safety has reached a
level where we go through each month with a
disappointing five or six lost time injuries,” says
Modikwa Business Leader Sean O’Connor.
For O’Connor, upping the ante even further
requires a whole-system approach which
combines interventions into ‘soft’ systems such as
procedures, communication and relationships with
July - August, 2010
‘hard’ systems approaches such as safer blasting
technology. O’Connor shares with us some of the
key ingredients in Modikwa’s quest to achieve the
vision of “zero harm”.
them not just as a resource but as an individual
with loved ones, with responsibilities and as a
breadwinner on whom his/her family depends,”
says O’Connor.
The Quest for “Zero Harm”
On an operational level, explains O’Connor, “The
most essential criteria are that our development
is being done in the right place at the right time
and at the required rate by creating reserves on
the right half levels and in the required quantity
to afford the depletion rates; doing our equipping
and mining sequences adequately; and reviewing
the planning to focus on the detail and do the
various risk ratings so that we can prematurely
predict problem areas and take timely corrective
action.
Communication plays a major role, and safety
issues are constantly discussed and monitored
at all levels. Employees’ higher educational
standard (matriculation or above) and ability
to communicate in English assist in facilitating
communication around safety matters.
This has been a major contributor to our reduced
fall-of-ground incidents.” On a human level,
O’Connor cites a passion for people, good
communication, strong relationships and shared
values as crucial to achieving a safe mine.
“We do not work to achieve superior safety
performance records of millions of shifts or to
increase the time interval between fatal accidents.
Instead, we have developed a passion to work
safely because we do not want to have any of our
employees killed in a mine accident at Modikwa.
They all have families and we see each of
July - August, 2010
Another boost for general health and safety is that
Modikwa’s employees live with their families and
are bussed to work and back each day, rather
than living in single-sex hostels.
Attention is also paid to relationship-building – both
between miners and management, and between
mine, labour organisations and the government.
“We work hard at maintaining a good relationship
with our labour organisations. Any stresses or
unresolved issues can impact negatively on the
relationship and then ultimately on their members
in the workplace,” says O’Connor.
An indication of their mutual support, management
and members of the labour organisations have
their own physical gesture, a two-fingered salute
accompanied by the phrase, “Staan saam!” (stand
together.)
6 million fatality-free trophy handover
35
The result of this relationship-driven approach is a
tightly-knit community that is personally invested
in looking after itself. “With every incident we
design ways and means of doing it differently to
avoid any potential repeat,” says O’Connor. This
brings us to the role of technology in incident
prevention.
Using Technology to Improve Safety
Established in 2000, the 450m deep Modikwa
mine utilises a hybrid mining system combining
trackless footwall development with conventional
narrow on-reef strike scraper mining. Modikwa
was a continuous operation working a 7-1, 7-2,
7-4 cycle until March 2009 when it converted to
an 11-day fortnight cycle.
Shock tube blasting has been used since the
mine’s inception, and blasting takes place at
0600 hours and between 1700 hours and 1800
hours daily. Several incidents of premature blast
initiation took place in 2005 and 2006.
Under construction: The 12km tar
road constructed by the mine to link
the Maandagshoek Clinic to three
surrounding villages
The failure of various system-based remedial
measures pointed eventually to an external
source – lightning – as the source of premature
initiations. Following two incidents in late 2006,
the mine acquired lightning detectors to indicate
when lightning was probable.

A fourth incident occurred in March 2007 when
two areas at the south shaft operations were
affected at the same time during a severe
afternoon thunderstorm – one on the RAW level
40m below surface, and the other, for the first time
ever, at 4 level, some 250m below the surface.
This showed that the risk of premature initiation
was not limited to the shallow areas of the mine
only, and was influenced by the level of insulation
of the blasting systems from the rock itself and/or
any metal in contact with the rock.
The OEM, AEC Electronics, investigated the
initiation system and the cabling installation and
came to the conclusion that the damage on the
system could have been attributed to reverse
currents into the output side of the system. This
may very well have been induced by stray currents
from the lightning on the day.
The standard for blasting cable installation and
insulation was changed and communicated, but
yet another incident occurred during April 2007.
Various alternative systems were investigated
to find an alternative, fail-safe system to prevent
lightning-induced blasting initiation.
Parallel to this, the Instantaneous Electric
Detonators (IEDs) used to initiate the blast were

replaced. (The IEDs were considered dangerous
because they cause a virtually instantaneous –
rather than sequential and thus safer – detonation
of some 140 shot holes.)
A system was introduced incorporating a Shurstart
and Igniter Cord combination to prevent the direct
initiation of the blast. The threat posed by lightning
was the danger posed by any stray current – that
is uncontrolled electricity – which could pass
through a detonator while it is being used.
Static electricity, electrical power lines, current
leakage, RF transmitters and galvanic currents
within conductive seams in the rock itself, all pose
an equivalent risk, though in this case not quite as
great as that posed by lightning – both direct and
indirect – in the Modikwa mining area.
The Highveld region of South Africa and Lesotho
is known to have one of the highest lightning strike
rates in the world, with each square kilometre of
the 104km2 Modikwa mining area receiving four to
six strikes per year – amounting to between 416 to
624 strikes annually over the entire area.
The risk is exacerbated by the fact that charging
up for afternoon blasting takes place during the
time when the lightning risk is greatest.
July - August, 2010
MagnaStart Centralised Blasting
System
The MagnaStart Centralised Blasting System,
produced by AEC Electronics, was eventually
installed at Modikwa in March 2007.
A derivation of the MagnaDet system used in
shaft sinking in the late 1980s and early 90s, the
MagnaStart system uses a magnetic toroid (aptly
nicknamed a lifesaver thanks to its donut shape) to
induce current at a certain frequency magnetically
into the instantaneous electric detonator.
“MagnaStarts can only be initiated by an
alternating current of frequencies in the region
of 10 to 100kHz for a duration of several
milliseconds,” explains Sean O’Connor. “This
reduces accidental initiations that could arise
from stray current mains-induced voltages, static
electricity, lightning strikes and electromagnetic
radiation (radio/microwaves).
As there are potentially no electrical joints to be
made when using MagnaStarts, the possibility of
current leakage is practically eliminated.”
A lightning strike at Modikwa shortly after the
commissioning of the MagnaStarts in April 2007,
caused premature initiation of conventional
Sehlaku & Mamphahlane Tribal Offices.
Tribal offices constructed for the
Sehlaku and Mamphahlane villages
37
initiators – but no misfires or premature firings
on the MagnaStarts (even though they were
more exposed to lightning than the conventional
initiators).
The MagnaStart system was clearly the right
solution. Monitoring systems continue to monitor
the standard of installation of blasting cables
and wires, and best-practice personnel safety
measures are also implemented to ensure the
reduction of the risk of premature blast initiation,
by lightning and other means.
4-way Clip Initiation System
Modikwa’s explosives accessories suppliers,
Northern Explosives, are currently involved in the
process of converting the mine’s 280 000 holes to
Master Blaster’s 200/4000ms, 4-way clip initiation
system which totally removes the out-of-hole
detonators from the rock face. By adopting this
system Modikwa not only eliminates all current
risk associated with the out-of-hole detonators,
but removes any chance of misfires occurring
through cut-offs from plastic shrapnel caused by
the detonation of the out-of-hole plastic blocks.
The mine has undertaken to make
contribution funds available for the
construction of two community halls, a
bakery, a sewing factory and tribal offices
in a number of the surrounding villages.
38
The system is extremely user-friendly, making
training simple and straightforward while producing
fewer gasses during detonation.
Master Blaster’s Managing Director, Mark Davis,
is full of praise for Modikwa’s commitment to
mine safety. “Anglo Platinum’s CEO Neville
Nicolau asked his group to ‘engineer out the risk’
to improve safety,” Davis recalls. “Sean and his
Modikwa team have taken this call very seriously
and their open approach to any change that
enhances safety on the mine can be witnessed by
the mine’s incredible safety record.
As suppliers of the most dangerous products
going underground we often ask the question, ‘If
the mines are serious about safety why dont they
use the safest products available to them?’ With
Sean and his team, you do not have to ask.”
“We Care – Re-a-Hlokomela”
The Re-a-Hlokomela safety campaign embodied
the message that “Modikwa Cares” about its
people and their wellbeing. Going beyond its
commitment to its employees, the mine has also
funded numerous socio-economic development
projects in the villages surrounding the mine.
“The interests of these seven villages are
represented by ARM Mining Consortium Limited,
which as a joint-venture partner of African
Rainbow Minerals (ARM) has an 8.5 percent
share in Modikwa Mine,” says O’Connor.
July - August, 2010
Cross section of four-way clip
“Till now, the Section 21 companies comprising
the ARM Mining Consortium have been repaying
the loan for their percentage ownership and have
not yet received any dividends. In the interim, the
mine has undertaken to make contribution funds
available for the construction of two community
halls, a bakery, a sewing factory and tribal offices
in a number of the surrounding villages.
We also funded a R63 million (US$8.6 million),
12km tar road linking the local clinic to three of our
villages. In the future, we look forward to these
communities becoming self-sustaining as a result
of the income they will derive from their shares in
the mine.”
At the same time, O’Connor concludes, there will
always be poverty on the mine’s doorstep, and
the mine will “continue driving for the upliftment of
the people and the community” – a strategy very
much in line with the vision of Patrice Motsepe,
Executive Chairman of ARM.
Those are firm foundations for a mine that is
just ten years old – ones which, both for safety,
wellbeing and indeed productivity – definitely
bode well for the future.

Fully automated sampling and analysis
system supplied to Modikwa Platinum
Mine in Mpumalanga
It is conventionally accepted that any
concentrator requires analysis of feed,
concentrate and tailings to ensure optimal
recoveries. Process changes are made
according to these analyses.
Historically Platinum concentrators were
receiving process analysis up to three days
later and this situation is still occurring.
Naturally there can be limited process
control with late assays and recoveries can
be affected.
Additionally the manual nature of the
sampling and analysis can lead to
unintentional human error, e.g. sample
switching, preparation errors, sample
overlapping etc. The turnaround times
of the current practice at concentrators
was recognized as a potential problem at
Modikwa and a decision was taken to install
a fully automated sampling and analysis
system.
The system was procured from IMP and the
scope of supply was as follows:
• Fully automated primary as well as
secondary sampling system
for sample collection
• Fully automated sample preparation –
filtering, microwave
drying, fine pulverizing and fluxing
• Fully automated sample analysis –
fusion, lead-separation, and
analysis by Optical Emission
Spectroscopy (OES)
• The system is termed FIFA (Fast In-Line
Fire Assay)
The sampling and “FIFA” laboratory allows
for a sample to be taken on an automated
pre-determined basis as well as on an
ad-hoc basis. “Snap-shot” analyses of
any sampling line can be requested and
results are available within 1 hour. Routine
compositional sampling and analysis will
deliver results within 3 hours.
The faster accurate information is received
of the process, the faster decisions can be
made on how to improve or increase the
effectiveness of any one of the processes,
or the complete plant as a production unit.
The turn-around time for Modikwa changed
from 36 hours to an average of 2.5-3 hours,
depending on how the sampling was set
up. Ultimately, how this information is
integrated, presented and used determines
the value of the fully automated laboratory,
and this contributed to improved process
efficiencies at Modikwa
Let IMP design and equip your next analytical
laboratory
IMP is the global leader in turn-key mining laboratory design and implementation with automated, semi-automated
and manual facilities in most industries from Aluminium to Zinc, from Sampling to Analysis. IMP also supports,
maintains and in some cases, even operates the laboratories. With offices in South Africa, Australia, USA and Brazil,
IMP is well positioned to provide an innovative solution for sampling, sample preparation and analytical laboratory
requirements within the mining industry.
