Giant leap in copper leaching technology Mineral
2015-6-1 Giant leap in copper leaching technology. The top ore layer of an open pit copper mine is easily processed using heap leach in tandem with solvent extraction and electrowinning to produce copper cathodes. The copper mineral most predominate in mines is however chalcopyrite (CuFeS 2 ), a refractory sulfide mineral that is found deeper in the mine.
