Abstract

The electrolytic cell has a trough-like container with a bottom, with side walls and with at least one inlet and at least one outlet for the electrolyte. Numerous plate-like electrodes are disposed in the container and are partly immersed in an electrolyte bath. The bottom of the container which is in contact with the electrolyte bath has numerous openings for the passage of electrolyte, and below the bottom there is disposed at least one distribution chamber for recirculated electrolyte. At least one of the side walls of the container is equipped with at least one recirculation chamber for recirculating electrolyte from the electrolyte bath into the distribution chamber, the upper portion of the recirculation chamber being connected with the electrolyte bath and the lower portion of the recirculation chamber communicating with the distribution chamber.
