Abstract


The cementation of gold with powder of zinc, from solutions with thiosulphate and ammonia, was studied. The variables evaluated were: thiosulphate concentration, ammonia concentration, pH, copper concentration and zinc concentration. The results have revealed the great importance of ammonia/thiosulphate relationship in this process and that the impurities presence like copper and zinc will to inhibit the cementation process.
