<p>A process is described for the selective recovery of nickel values from an aqueous solution containing nickel values by means of liquid/liquid extraction, wherein the aqueous solution is contacted with an organic extractant comprising a substantially water-immisicible organic solvent and one or more of certain alpha,beta-dioxime compounds. Novel alpha, beta-dioxime compounds for use in the extraction process are also described.</p> |
