AbstractThe solvent extraction of gold from thiosulfate solutions with alkyl amines was studied. The experimental results showed that with both aliphatic and aromatic hydrocarbons as diluent, the power of amines for extraction of gold decreased in the order: primary > secondary > tertiary amine. Further study indicated that the initial gold concentration and ionic strength in aqueous phase had no significant influence on the extraction of gold with primary amine N-1923 The extraction of gold at high pH values increased with an increase of the extractant concentration. The enthalpy change for the extraction with N-1923 was calculated -120.8 kJ mol(-1). From these experimental results, the equations of extraction of gold with N-1923 from thiosulfate solution with and without the presence of ammonia have been derived respectively.; The solvent extraction of gold from thiosulfate solutions with alkyl amines was studied.
