Processing: – Copper

· Copper Ore which contains less the 1% copper is mined and then transported to be refined, some common copper ores include copper oxide and copper sulfide. Copper however, is far more available in Chalcopyrite and Bornite and can be processed by means of mineral refinery, smelting, leaching and electrolysis. (Copper, 2017) Mineral processing involves breaking.
