Recovery method of copper electrolysis permanent stainless steel cathode

Abstract

The invention discloses a recovery method of a copper electrolysis permanent stainless steel cathode. The method comprises the steps that preprocessing and specific recovery are carried out; when a conductive beam breaks off, an old copper plating layer of the stainless steel cathode is removed firstly, the conductive beam is separated from a polar plate, then the polar plate is leveled, a new conductive beam is welded, and at last a new copper plating layer is electroplated again; when the polar plate is locally damaged, the old copper plating layer is removed firstly, the conductive beam is separated from the polar plate, a new polar plate is welded, and a new copper plating layer is electroplated again; and when the copper layer bumps, the copper layer is cleaned with clean water firstly to make copper sulfate crystals at the bump dissolve and flow out, then the bumping copper plating layer is attached to the face of the polar plate, and finally the copper plating layer is subjected to supplementary electroplating. By adopting the recovery method for recovery of the copper electrolysis permanent stainless steel cathode, the labor intensity of workers can be relieved, the recovery efficiency can be improved, accordingly, the service life of the stainless steel cathode is prolonged, cost is reduced, and thus the quality of electrolysis copper products is improved.

Description

technical field [0001] The invention relates to the field of electrolytic copper production, in particular to a method for repairing copper electrolytic permanent stainless steel cathodes. Background technique [0002] The permanent stainless steel cathode used in the production of electrolytic copper will produce various defects and damages that do not meet the requirements of the production process. The existence of defects and damages will affect the product quality of the output electrolytic copper, and will also cause the electrolytic copper to automatically peel off Difficulties, thereby affecting production efficiency; discarding defective and damaged permanent stainless steel cathodes will cause waste and increase costs. The existing repair methods for permanent stainless steel cathodes have high labor intensity for workers, low repair efficiency, and high repair costs. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the inv...
