A process for the recovery of nickel and cobalt from an acidic resin eluate containing at least nickel and cobalt, said process including the steps of : (a) treating the eluate with an immiscible organic reagent (18) to selectively absorb the majority of the cobalt, and a portion of any copper, zinc and manganese present in the eluate, leaving a raffinate containing the nickel and minor impurities; (b) neutralising the raffinate to precipitate the nickel as nickel hydroxide (19); (c) stripping the cobalt from the organic reagent (22); and (d) recovering the cobalt (23). |
