Abstract:
The invention relates to a method and an apparatus for preparing a mother plate of a permanent cathode to be used in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning. The apparatus comprises a holder for releasably holding the permanent cathode, a measurer for measuring a shape of the mother plate to obtain measurement data, a calculating device functionally connected with the measurer and configured for calculating geometric deviation of the mother plate in comparison to a predefined reference shape by using the measurement data, and a presser functionally connected with the calculating device and configured for automatically locally pressing the mother plate in accordance with the calculated geometric deviation of the mother plate to plastically deform the mother plate.
