Abstract:
Device for separating metal deposit from a mother plate used as a cathode in an electrolytic process, as metal electrorefining or metal electrowinning, in which device there is a supporting member for supporting the cathode to be treated, a member for releasing at least partly a metal deposit grown during the electrolytic process on a surface of the mother, the mother plate of a cathode providing with a growth affecting means for creating an irregularity in the growth of the metal deposit, and a member for supporting the released metal deposit, characterised in that a growth affecting means (16,24,36,43,53) for creating an irregularity in the growth of the metal deposit (4) is on the edge or on the vicinity of the edge of the mother plate of the cathode (1,21,31,41,51) a groove with the walls in acute angle to each other so that the groove is the broadest at the surface of the mother plate of the cathode (1,21,31,41,51), and the growth affecting means (16,24,36,43,53) is used as a hinged member when the metal deposit (4) is tilted to the mother plate of the cathode (1,21,31,41,51) in order to break the metal deposit (4) in two separate pieces along the irregularity in the growth.
