Copper Ore Processing Plants, Flow And Equipment
Copper industrial minerals include: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. Chalcopyrite (a compound of copper, sulfur, and iron) is mined mainly, followed by chalcocite and bornite. If copper ore wants to be fully utilized, it must be processed by flotation. Flotation separation is an important copper ore beneficiation …
