REDUCING POWER CONSUMPTION IN ELECTRO-REFINING OR ELECTRO-WINNING OF METAL

摘要

A cathode plate for electro-refining or electro-winning of metal. The cathode Comprises a cathode blade (100) and hanger bar (300). A quantity of electrically conductive material (350) is wrapped around the hanger bar and along the cathode blade (400) to a position, in use, proximate the level of electrolyte (500) in the electrolytic bath. The provision of a deeper and preferably thicker coating of electrically conductive material, as compared with conventional cathode plates reduces plates reduces power consumption in the electrolytic circuit.
