The recovery of cobalt, in this nickel refining process, is much lower than that of nickel, as a result of the adsorption of cobalt by the iron oxide leach residue. Furthermore, the selectivity of the reduction process, for nickel, depends on the maintenance of a low level of cobalt in the purified leach solution.
