ABSTRACT:
A method of electrowinning a metal in which electrolysis and servicing and treatments of the electrodes are carried out using an electrode unit. A plurality of anode plates and cathode plates are allunately and insulatedly assembled and regularly spaced and secured. By use of such electrode units, the anode plates and the cathode plates can be arranged closely-spaced, and thus the efficiency of electrolysis is enhanced, the electrolytic cell can be made compact, and the operation space can be reduced. Also, this method is suitable for automation of an electrowinning operation.
