ABSTRACT:
A method of manufacturing a cathode plate (1) that is used in the electrolytic cleaning and recovery of metals, the cathode plate being at least partly manufactured of stainless steel and the surface of the cathode plate being treated in at least one stage, whereby the cathode plate is formed by cutting it from a solid plate-like material (2), whereby, essentially before cutting (4) the cathode plate to shape, at least part of the surface constituting the cathode plate is subjected to a mechanical treatment (3) to improve the adhesion properties of the surface. The invention also relates to the cathode plate.
