PCT No. PCT/SE96/01000 Sec. 371 Date May 27, 1998 Sec. 102(e) Date May 27, 1998 PCT Filed Aug. 9, 1996 PCT Pub. No. WO97/07263 PCT Pub. Date Feb. 27, 1997The present invention relates to an improved cathode element for the production of electrolytic copper, and more particularly to an improved cathode element of the reusable type which includes a cathode plate. With the intention of preventing a sleeve-like copper build-up around the cathode plate, the cathode element is provided with electrically insulating edge strips along at least those side edges of the cathode element which, in an active position, are located in the electrolyte bath, wherein the electrically insulating edge strips are chemically bonded to the cathode plate, preferably by vulcanization or by gluing. |
