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 02% and 5% copper, with gold ,
An oxide gold ore was subjected to chloride/hypochlorite leaching at room temperature The effects of three factors, including Ca(OCl) 2 vs NaOCl, OCl − concentration, and HCl concentration on gold leaching performance were investigated Due to formation of CaOCl + complex in solution and hence less reactivity, calcium hypochlorite produces a sluggish gold ,
