PACKED BED ELECTROREFINING AND ELECTROLYSIS

摘要

A molten metal, such as aluminium, is refined by passing a stream thereof into an anode comprising a bed of conductive particles, such as carbon, in a molten or conductive-solution salt bath. A diaphragm, pervious to the salt but impervious to the molten metal, separates the anode from a cathode also comprising a bed of conductive particles in a salt bath which is in molten or in conductive solution condition.
