| Abstract: | It was showed that gold can be extracted from alkaline cyanide solution by synthetic sulfoxide MSO. If a certain quantity of alcohol P containing high carbon is added in oil phase, the extraction performance of gold can be improved markedly. The oil phase containing 45% P (V/V) and MSO of 1.3 mol/L can extract gold very quickly, and the extraction was over 94%. Gold can be stripped by sodium hyposulfite. The stripping of gold preponderates over 97% was obtained by the sodium hyposulfite solution with concentration of 40 g/L. |
