iron oxide copper gold deposits processing methods

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 to >4,000 million tonnes of contained ore, and have a grade of between 02% and 5% copper, with gold contents ranging from 01 to 141 grams

Gold-Copper Ores ScienceDirect

2016-1-1  Flotation and smelting are currently preferred for copper sulfide ores, but as yet there is no practical alternative to cyanidation for copper oxide ores. Iron–oxide–copper–gold (IOCG) deposits, however, are often amenable to flotation to generate a Cu–Au concentrate, with the recovery improving down through the orebody from the oxide zone to the transition and primary zones.

Gold in iron oxide copper–gold deposits ScienceDirect

2016-1-1  Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirty-six deposits in some well-defined IOCG
