copper extraction and refining

Copper Refiningan overview ScienceDirect Topics

Solvent extraction has been routinely used for copper refining since its invention in the 1960s and it is suggested that well over 10 of refined copper production from ores is obtained by solvent extraction accounting for millions of tonnes of metal. It is even more popular for refining copper from scrap.
