An anode box sized and configured for retaining an anode plate therein is disclosed for use in an electrolytic tank of the type used for electrowinning or electrorefining. The anode box is unitarily formed, thereby rendering the device more resistant to degradation typically caused by the harsh environment of the electrolytic tank. The anode box is also formed with spacer structures which protect and isolate the anode plate from contact with the diaphragm, when used, and from contact with adjacent cathode frames. The anode box may include other elements, such as a port through which liberated gases may be withdrawn.

Anode box for electrometallurgical processes

A cathode frame for receiving and retaining a cathode plate for electrowinning and/or electrorefining processes is constructed as an integrally-formed frame body having a base member and side members which provide a continuous channel therethrough for retaining the peripheral edge of a cathode plate, and is further structured with a cross frame extending between the side members for receiving a cathode plate therethrough. The cross frame is sized and positioned to extend proud of the frame body thereby providing contact surfaces for striking when recovering the cathode plate from the frame. In an alternative embodiment of the invention, the cross frame is integrally formed with the side members and base member and the cathode frame is configured to retain a filter media thereagainst.
