A copper electrolytic refining method by the series process, which comprises forming a copper strip of undefined length by a continuous casting process, cutting that strip into pieces of lengths such that plates are formed having the required surface area, submerging the cut pieces as unrefined electrodes in series in an electrolyte solution contained in a tub whose inner surface is made of an electrically insulating synthetic polymer material substantially inert to the electrolyte solution, maintaining the electrolyte solution at a temperature of at least 54º c, and pass a continuous current through the electrolyte solution to make it dissolve in the copper solution of one of the electrodes and deposit as pure copper on another of the electrodes.
