Alkali metal mercaptide solvent extraction of cobalt, nickel |
摘要 |
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 anions are generated by solubilizing an alkali metal mercaptide in a polar organic solvent capable of solvating alkali metal ions. Alternatively, an organic solution of a mercaptan is exposed to an aqueous solution of NaOH or KOH to produce the mercaptide anion.
