Scrap Copper Cathode Making Equipment Copper Refining Plant
The refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 99.99% through an electrolysis process: During electrolysis, copper (II) ions leave the impure copper anode and since they are positive, migrating to the negative cathode. From time to time, the pure copper is scraped off the cathode.
