Coated valve metal anode for electrolytic extraction of metals or metal oxides

Abstract From the Canadian patent

An electrode comprises a horizontally arranged current feed which is formed by a rail of copper or has such a rail as a current conductive component. From this rail at least one current distributor branches which is con-, structed of a sleeve of valve metal and a core arranged therein, and of a metal which is a good electrical conductor which is in electrical connection with the sleeve and in which preferably a contact structure is embedded which consists of valve metal and is connected to the inner surface of the sleeve by a plurality of weld positions. To the sleeve of the current distributor an active part of the electrode is mechanically and electrically conductively connected. The …
