iron oxide copper gold ore processing

Iron oxide copper gold ore deposits - Wikipedia

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...
