摘要：

The extraction of gold from thiosulfate solutions with alkyl phosphorus esters was studied. The experimental results showed that the gold can be extracted only in alkaline thiosulfate solutions. The gold recovery increases with the increase in concentrations of thiosulfate in the aqueous phase and of alkyl phosphorus esters in the organic phase respectively. Compared with aliphatic hydrocarbon diluents, aromatic hydrocarbons tested are unfavorable to the gold extraction. The addition of ammonia to thiosulfate solutions has a strong influence on the mechanism of the extraction of gold. (C) 1997 Elsevier Science B.V.
