Abstract

There is described a method for electrolyzing and particularly electrorefining metals such as copper, by circulating the electrolyte through channels formed between substantially parallel electrodes arranged some distance away from one another, in which a substantially uniform electrolyte flow rate is retained at least at the inlet to the channels between the electrodes, independently from the cathode thickness increase and the anode thickness decrease during the electrorefining. A device for working this method is also described.
