Solvent extraction and electrowinning

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.
