ABSTRACT:
A method is disclosed for separating cobalt from nickel which consists essentially of adjusting the pH of a cobalt chloride solution containing nickel to about 3 to about 5 with a base, adding hypochlorite to the resulting pH adjusted solution in an amount equal to at least the stoichiometric amount required to oxidize essentially all of the cobalt to the .sup.+3 state, while maintaining the pH at about 3 to about 5 by addition of a base, to form a solid containing at least about 60% by weight of the cobalt in the .sup.+3 state and a liquor containing essentially all of the nickel, and removing the solid from the liquor.
