摘要： Metal, e.g., copper, is electrolytically refined by a series process in which the intermediate electrodes are removed from the tank of electrolyte solution before all the impure metal has been dissolved from them, and each partially refined intermediate electrode so formed is passed in turn through apparatus which mechanically separates the pure and impure metal of the electrode. Preferably the electrode-separating apparatus distorts the pure and impure metal of the electrode to such an extent that they are separated. The separated pure and impure metals of each electrode are preferably conveyed from the electrode-separating apparatus along separate predetermined paths. All these operations are preferably effected automatically.
