An electrowinning cell for metal electrowinning comprises an anode and a cathode with the cell having an electrical field in the interelectrodic space between the cathode and the anode. The cathode comprises a hollow electrode which defines an interior and includes conductive metallic cathodic plates with orifices in the cathodic plates. The anode is positioned externally of the hollow interior of the cathode. The electrolyte can be introduced with the necessary pressure into the interior of the cathode in order that the electrolyte flows to the interelectrodic space through the orifices and is subjected there to the existing electrical field. Electrodeposition of cations to form a metal deposit on the external surface of the cathodic plates then takes place. The orifices are formed in insulating inserts in the conductive metallic plates in order to avoid metal deposition around the orifices. |
