  • Leaching of an oxidegold ore with chloride hypochlorite

    Jun 01, 2007· An oxidegoldore was subjected tochloride/hypochlorite leaching at roomtemperature. The effects of three factors, including Ca(OCl) 2 vs. NaOCl, OCl − concentration, and HCl concentration ongoldleaching performance were investigated. Due to formation of CaOCl + complex in solution and hence less reactivity, calcium hypochlorite produces a sluggishgoldleaching kinetics, taking twice ...
