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.
