The synergistic effect of a mixture of bis(2-ethylhexyl) sulfoxide (BESO) and primary amine N1923 in kerosene on the extraction of Au(I) from alkaline cyanide solution was investigated. Experimental results demonstrate that addition of BESO into the organic phase can significantly enhance the basici...
