ABSTRACT:
Apparatus for electrolytically refining copper by the series process comprises a tank having an inner surface of an electrically insulating synthetic polymeric material that is substantially inert to an electrolyte solution to be contained in the tank and, associated with the tank, baffles for reducing current flow that would otherwise occur around the edges of electrodes when immersed in the electroltye solution. These baffles comprise sheets of an electrically insulating material that is inert to the electrolyte solution. A pair of such sheets constitutes side baffles each of such a shape and size that it can be positioned with its major surfaces vertical between side edges of a group of electrodes when immersed in the tank and a neighboring side wall of the tank throughout the length of the group. A plurality of such sheets constituting bottom baffles form a self-supporting lattice work structure and are so arranged and of such a shape and size that, when the lattice-work structure rests on the base of the tank, the bottom baffles will be mutually spaced along the length of the tank and will be positioned with their major surfaces vertical in the gap between the base of the tank and the bottom edges of electrodes when immersed in the tank with each bottom baffle extending transversely of the tank throughout substantially the whole of the width of the electrodes.
