Key design criteria and challenges
Customer
challenges
Outotec
solution
• World’s largest Solvent Extraction
plant by PLS feed rate
(PLS = Pregnant Leach Solution)
> 11,000 m3/hour
> 3,000 liters per second
• VSF Solvent Extraction and Electrowinning
references from world’s largest operations to
date
• Outotec Performance Guarantees and track
record
• High level of impurities in the feed leading to
crud build-up
• Deep settler design enables more sensitive
control to minimize impact of impurities
• Knowhow in SX-EW process & plant design
for a wide range of applications
• Iron, Aluminum
• Solid particles
• Fulvic Acid
7
• Total Project Capital cost
USD 440 M
• Use of VSF SX & EW equipment from the
suspended Tia Maria project (valued ~USD
90 M) plus complementary Engineering,
Equipment and Site Services
~USD 40 M
• Bring Buenavista del Cobre back on growth
track; time to First Copper as soon as possible
• Reduction of project time up to 6 months by
re-using Tia Maria designs and equipment

Value of Outotec VSF™ SX and EW
technology
4
• Outotec VSF Solvent Extraction;
• CAPEX
- Reduction of footprint up to 50%
compared to Conventional technology
- 40% smaller first organic fill
• OPEX
- Better design leading to minimized
losses of organic fluid
- More flexibility to operate under difficult
conditions (crud) due to deep settler
design
Conventional SX
• Outotec Electrowinning technology
• CAPEX
- Smaller & simpler plant
• OPEX
- Lower energy consumption through
design
- Safety due to fully automated cathode
harvesting and stripping
