Abstract
For replenishing a plating bath with copper or other metal to be electrodeposited with the use of an insoluble anode, scrap metal such as copper wires is received in a makeup tank, into which are passed the gases generated within the plating tank with the progress of electroplating operation. The plating solution in the plating tank is also directed into the makeup tank and sprayed on the scrap copper wires, thereby dissolving same. The dissolved copper is then filtered, heated, and introduced into the plating tank.
