ABSTRACT:
Cobalt, copper and nickel values are separated from ammoniacal aqueous solutions by contacting the solutions with a chelate exchange resin of polymerized ar-vinylbenzylamino dicarboxylic acids whereby the cobalt, copper and nickel values are loaded on the chelate exchange resin, stripping the cobalt, copper and nickel values from the loaded chelate exchange resin by contacting the loaded resin with a mineral acid and restoring the capacity of the chelate exchange resin when it falls below a predetermined value by reacting the degraded chelate exchange resin with an aqueous solution of a halo salt of a carboxylic acid, the aqueous solution being maintained at a pH value greater than about 8.
