ABSTRACT:
A technique and arrangement for the continuous electrolytic refining or electric extraction from solution of copper or other non-ferrous metal is described. An elongated electrolysis chamber is divided into a pair of separated compartments by means of a membrane which is permeable to the electrolyte used in the process but impermeable to solid, sludge-like impurities generated at the anode of the installation during electrolysis. The anode is fixedly supported in a receptacle disposed in one of the compartments, while the cathode, which preferably is in the form of an elongated continuous rod of circular cross-section, is supported for continuous longitudinal movement through the other compartment. The interface between the moving cathode and the adjacent electrolyte in the associated compartment is preferably agitated in order to increase the speed of transfer of the metallic ions and associated surface-active substances in the electrolyte to the cathode surface.
