U S Pat 3 764 493 1973 Oct; :
Ni and CO are separated and recovered from ores or alloy scrap by selective cathodic reduction and deposition of ni in a galvanic cell. The galvanic cell employs separate cathode and anode sections, a ni cathode, a CO anode, and a fused salt electrolyte. The catholyte and anolyte compartments of the cell are connected by a porous diaphragm, while the cathode and anode are directly electrically connected externally.
