For a refractory ore, pretreatment is required in order to expose the gold surface to the leach solution. An acidic hypochlorite solution can be added to the autoclave for pressure oxidation and extraction of the gold at the same time. It required 50 % sodium hypochlorite or 120 kg/t available chlorine to extract 97 % of the gold from the ore.
