AbstractThe extraction of gold from thiosulfate solutions with a mixture of neutral reagents and amines was studied. A combination of the primary amine N-1923 and the neutral donor reagents, such as alkyl phosphorus eaters, was found to be the most effective solvent for the extraction. Using slope analysis, the compositions of the gold extraction species in mixed organic solvents with N-1923 and tributyl phosphate (TBP) were investigated. The effect of N-1923 and TBP in the mixed organic phase on the extraction is not the same for different ranges of aqueous pH. It may be proposed that with an equilibrium pH < 9, N-1923 is the main extractant with TBP as a synergistic reagent, while with an equilibrium pH > 9, N-1923 shows a synergistic effect on the extraction of gold with TBP.
