Electrorefining | metallurgy | Britannica
In electrorefining, the nickel is deposited onto pure nickel cathodes from sulfate or chloride solutions. This is done in electrolytic cells equipped with diaphragm compartments to prevent the passage of impurities from anode to cathode. In carbonyl refining, carbon monoxide is passed through the matte, yielding… Read More; tin
