ABSTRACT:
A cathode for metal electrowinning is a hollow electrode, with orifices in the cathodic plates, formed in such a way that the catholyte, introduced with the necessary pressure in the interior of the cathode, goes to the interelectrodic space through those orifices, and is subjected there to the existing electrical field, taking place then the electrodeposition of the cations on the external surface of the cathodic plates.
