Copper extraction - Wikipedia

As with oxide ores, solvent extraction and electrowinning technologies are used to recover the copper from the pregnant leach solution. Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media.
