Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting After crushing the ore to a fine powder, it is then concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic The mixture is.
