Abstract (en)
[origin: WO2020005147A1] The present invention relates to an edge protection (7) intended to be used in electrolysis for purification of copper, wherein an anode and a cathode are immersed in an electrolytic solution (2) and wherein current is supplied to the cathode (1), which is a negative pole, and the anode is a positive pole, whereby impure copper, after collecting electrons, becomes pure copper and sticks to the cathode (1), which is an outspread plate formation, wherein the edge protection (7) in use is placed over and around an edge (9) at at least one free side (5,6) of the cathode plate (1). The edge protection (7) comprises at least an elongated first portion (11) mounted to the cathode (1) for receiving and retaining at least a second elongated portion (12), which covers the edge of the cathode at a surface area (10) on each side (5,6) of the cathode plate (1), on each side (19,20) of the cathode plate's (1) edge, and an edge surface (9), substantially perpendicularly arranged relative to the cathode plate surfaces (10).
