A method for electrowinning a metal using an electrode unit consisting of assembled anode plates and cathode plates and a frame body for forming such an electrode unit.

摘要

A method of electrowinning a metal in which electrolysis and servicing and treatments of the electrodes are carried out using an electrode unit (1) which comprises a plurality of anode plates (2) and cathode plates (4) alternately, insulatedly assembled and regularly spaced and secured is disclosed. By use of such electrode unit (1), the anode plates (2) and cathode plates (4) 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 electrowinning operation.
