Abstract

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