ABSTRACT:
An electrode for electrolytic extraction of metals or metal oxides comprises a horizontally arranged current feed which has a copper rail as current feeding component. From this rail at least one current distributor branches, which consists of a sleeve of valve metal and a core arranged therein and consisting of metal which is a good electrical conductor which is in good electrical connection with the sleeve and in which preferably a contact structure is embedded. To the sleeve of the current distributor an active part of the electrode is mechanically and electrically connected.
The rail of the current feed of copper is provided in the region of the connection position of a current distributor with a connection element of valve metal which is connected to the copper rail via a separate copper element by explosion welding.
