Cadmium refining in chloride melts using a bipolar-electrode electrolyzer

摘要

A method is proposed for electrolytic cadmium refining in molten cadmium chloride with the use of bipolar Cd electrodes. The effect of electrolysis conditions on the refining process is analyzed, and the dis- tribution ratios of typical metallic impurities in Cd are evaluated. The results demonstrate that high-purity Cd can be obtained in a single electrolysis cycle.
