Abstract
An electrode assembly for use in electrowinning includes a cathode in the form of a plate. The cathode has a pair of parallel vertical edges, and a horizontal bottom edge which runs between the vertical edges and defines respective corners therewith. An edge strip is mounted on each of the vertical edges as well as on the bottom edge. The bottom edge strip has an end at either corner, and each end of the bottom edge strip is in abutment with the lower end of the adjoining vertical edge strip. A corner protector is located at each corner and has a vertical channel which receives the lower end of the respective vertical edge strip, a horizontal channel which receives the respective end of the bottom edge strip, and a cutout which receives the cathode.
Claims20
A corner protector for an electrolytic electrode having first and second edges which define a corner and are respectively provided with first and second coverings, said corner protector comprising:
- a body provided with a first channel portion for receiving the first covering and a second channel portion for receiving the second covering,
- said body also being provided with a cutout for receiving the electrode.
A method of making an electrolytic electrode assembly comprising the steps of:
- providing an electrode having a first edge, and a second edge which defines an intersection with said first edge;
- placing a first covering having a first end over said first edge so that said first end is in the region of said intersection;
- placing a second covering having a second end over said second edge so that said second end is in the region of said intersection;
- and
- confining said first end, said second end and said intersection in an additional covering.
