    • Iron oxide copper gold ore deposits

      Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging

      Virtually all sulfide type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.
