K-0504-KCC ABSTRACT OF THE DISCLOSURE A novel class of extractants and a method of using the extractants in the hydrometallurgical recovery of nickel and cobalt metal. The extractants comprise a water immiscible organic solvent system containing solubilized mercaptide anions. In an important embodiment of the invention, the mercaptide ions are generated by adding a mercaptan to a mixed water immiscible solvent comprising a basic compound such as an amine, preferably a tertiary amine, and a polar component such as an alcohol, whereby the mercaptan undergoes acid disso- ciation. The extractants are used by being contacted with cobalt, nickel, or cobalt and nickel containing aqueous solutions. On mixing, the cobalt and/or nickel values are taken up by the organic phase as cobalt or nickel mercaptides. These may then be stripped of cobalt and nickel by treatment with an aqueous alkaline solution and carbon monoxide.
