<p>The invention relates to a new design of a cathode for metal electrowinning. …<??>According to the invention, a hollow electrode (1) is provided with orifices (6) in the cathodic plates, 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. …<??>The invention is particularly useful in the production of metals through electrodeposition.</p> |
