Separate Nickel and Cobalt by Electrorefining
The electrolytic separation of nickel and cobalt by electrorefining in a molten salt electrolyte was shown to be technically feasible. Nickel-cobalt alloys containing up to 5.5 percent cobalt were electrorefined in a KCl-LiCl-NiCl2 electrolyte to a high-purity nickel metal meeting atomic energy specifications. The amount of cobalt transferred to the cathode deposit was found to … Read more
