Solvent extraction and electrowinning Wikipedia

Solvent extraction and electrowinning SXEW is a twostage hydrometallurgical process that first extracts and upgrades copper ions from lowgrade 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 electrolytic procedure
