Anodic electrogeneration of molecular chlorine from sodium chloride in an electrolytic cell produces a hypochlorous acid solution in an aqueous medium. This mixture of chloride and hypochlorous was used to leach gold from alluvial ore to its complex forms, [AuCl2]-, [AuCl4]-. The optimal amounts of NaCl in a neutral medium for gold leaching was 10 g L-1, while at pH 2, with a fixed NaCl concentration of 10 g L-1 it was observed a gold leaching increment of 70.4%. The addition of sodium hypochlorite to a solution of sodium chloride at pH 2 shows that it is the chloride oxidized product that performs the function of oxidant and can be used successfully for gold recovering from alluvial ore without the use of mercury.La electrogeneración anódi...
