Solvent extraction and electrowinning - Wikipedia

Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes using an ...

Apr 08, 2019  The CLC metallurgical plant relies on an atmospheric leaching process to recover copper from the rich Las Cruces chalcocite ore. A unique feature of the plant is the use of eight OKTOP agitated reactors to dissolve the copper under conditions of high temperature and high acidity. Oxygen is also added into the reactors to complete the reaction.
