| 摘要 |
The invention relates to a permanent cathode (3) that is to be used as electrode in the electro-refining and/or recovery of metals, such as copper, zinc, cobalt or nickel. The permanent cathode (3) comprises a planar mother plate (4) that is made of metal and comprises two sides (5). The mother plate (4) comprises an edge (6), which at least partly surrounds the metal plate. The edge (6) comprises a groove portion (8) that is provided with a groove (7). The groove portion (8) comprises at least one bridging section (9) for joining together, over the groove portion (8) of the edge (6) of the metal plate at the at least one bridging section (9), the cathode metal halves (15), such as cathode copper halves, cathode zinc halves, cathode cobalt halves or cathode nickel halves, which are formed on the sides (5) of the mother plate (4) in the electro-refining of the metals. |
