Group Profile
Mining
Solutions
This brochure is part of a series of publications with the purpose
of presenting Maccaferri’s range of solutions. Further technical
brochures, documentation, design guides, software and project
Case Studies are also available. For over 130 years, Maccaferri has
solved our clients’ geotechnical and engineering problems; from
evaluation and project definition to design and construction, we
continually accumulate experience and knowledge in this field.
For additional information or other technical publications,
please contact any Maccaferri office.
Although there are great differences between
the mining and civil engineering industries,
the engineering challenges are similar;
Maccaferri’s solutions are applicable to both
sectors.
Mining is one of the oldest human activities;
the first traces of activity are over 40,000
years old. The business of modern mining
follows strict environmental, operational and
remediation guidelines. These ensure that the
mined area can recover to at least its original
condition, and often better in many cases.
WITH OVER
130 YEARS OF
INTERNATIONAL
EXPERIENCE
Wherever your problem exists within the
lifecycle of the mine, Maccaferri products and
solutions can help. From access and materials
handling infrastructure, rockfall hazard
mitigation, product concentration and leachate
storage, to dewatering and site remediation,
please contact Maccaferri.

Processes
Open-cast Mine
Storage Zone
This is where the rock minerals are
accumulated.
Mineral Extraction Zone
Be it an underground mine or
an open-cast mine, minerals
are extracted through the
drilling of solid rock.
Dismantling Zone
Underground Mine
Storage Area
Crushing Zone
This is where the rock minerals are
crushed into smaller pieces.
Leaching Storage
Tailings Dam
Primary Crusher
Flotation
Treatment Zone
This is where minerals (previously deposited
in the leachate) receive treatment according
to their subsequent use.
Treatment Plant
Water Treatment Reservoirs
Leaching Zone
Minerals are extracted from the rocks
through a chemical process. In order to
carry out this process, the minerals need
to be placed into properly prepared areas.
The results of this process are collected in
two areas. In the pool storage are the
leached minerals and in the tailings dam
are the residues.
Water Treatment Zone
Water use is necessary in the various stages
of the cycle of a mine and this is where it is
treated and recycled.
Leaching Zone

Underground
Mines
Operating underground encompasses the
necessary processes and applications of specific
techniques to extract valuable minerals.
Maccaferri offers numerous solutions to line
tunnels to control loose and falling debris
that often occurs during mining operations.
Depending on the specific risks, these
solutions include steel or polymer meshes, or
fibre reinforced shotcrete.
Maccaferri’s high strength Pararib™ tunnel
lining polymer mesh is white in colour, flame
retardant and light to handle in confined areas.
Wirand steel and polymer fibres are added to
pumped shotcrete to reinforce it and provide
stabilisation of shafts and adits and can even
replace the traditional steel mesh. Rapid to
install, these solutions minimise disruption to
the extraction operation.

Opencast
Mines
Project
Experience
An opencast or open-pit mine is used to extract
valuable deposits close to the earth’s surface.
Here the fragmentation, loading, materials
handling and production control require heavy
equipment.
To maximise extraction volume and minimise
the space for infrastructure, slopes within these
mines can be steep. Material can detach from
these slopes affecting mine safety and operations.

Treatment
Process
The treatment process consists of the
operations after mineral extraction and until
a concentrated mineral is produced. Numerous
phases can include, fragmentation, graining,
milling, classification and concentration. At
each stage, Maccaferri offers solutions such
as reinforced soil and retaining structures for
crusher and hopper walls. Wherever possible,
the reuse of site-won structural backfill is used
with Maccaferri’s geogrids for reinforced soil,
reducing costs and material waste. Maccaferri’s
concrete panel wall system, MacRes ® offers
vertical structures with a tough fascia and with
geogrid strengths up to 1350kN/m, even the
heaviest vehicles can be accommodated.

Storage
Process
Project
Experience
The safe storage of tailings, waste, leachates
and toxic materials is a significant operation
within mines. Maccaferri’s range of solutions
includes geosynthetic membranes, geogrids
and drainage geocomposites. These are used
in heap leach pad liners, evaporation ponds
and lagoon linings. Containment dykes often
feature geogrid reinforced soil or gabion
retaining structures and major dump zones can
be supported on basal reinforced platforms.

Access
&

infrastructure
Effective access ramps, haul roads, surface
water control structures and drainage systems
are important to the uninterrupted performance
of a mine.
Whether a weak haul road requires sub-grade
stabilisation with geogrids, an outfall structure
requires erosion protection, or a run-off ditch
needs lining, Maccaferri can help based on our
130 years of experience in civil, geotechnical
and hydraulic engineering.

Closure
Project
Experience
Finally, the closure of the mine and the
reinstatement of the ecosystem is one of the
most important activities in the life of the
mine.
Maccaferri
offers
impermeable
capping
and drainage systems to prevent surface
water entering the deposits. The rapid reestablishment of vegetation and soil erosion
protection systems complete the closure
operations. Maccaferri’s wide range of manmade and biodegradable soil stabilisation and
erosion protection solutions facilitate this.
