The engineering challenge
Leaching, solution purification, SX and EW must stay coordinated to protect electrolyte quality and production stability.
The project followed the path from laboratory study to the design and construction of a copper cathode plant.
Zarfaravar’s delivery method
After six months of laboratory studies, crushing, leaching, solvent extraction and electrowinning were developed for the target feed.
- Six-month laboratory program
- Design crushing and leaching
- Develop SX and EW circuit
Decision-ready outputs
The project was defined for 300 t/day feed and 700 t/year cathode, with construction starting on 25 September 2021.
