Solvent extraction of trace concentration of gold(Ⅰ) from alkaline cyanide solution by extractants, tetra decyldi methyl benzyl ammonium chloride(TDMBAC), primary amine N1923, tri-n-octylamine(TOA) has been carried out by using a ¹⁹⁸Au radioactive tracer method. The influences of gold concentration, the molar ratio of extractant to Au(CN)₂^-, volume percentage of synergic reagent, phase volume ratio and salting-out agent have been studied. The results indicate that ¹⁹⁸Au radioactive tracer method is a quick, convenient, accurate method especially for extraction of trace concentration of gold. When the molar ratio of TDMBAC to gold (0.1 mg/L) is more than 50, the extraction percentage reaches 95%. The extraction percentage does not change much with the further addition of synergic reagent TBP(tributyl phosphate) after its volume percentage reaches 20%. Salt has little effect on the gold extraction. Stripping extraction of gold from such loaded organic phases was also discussed.
