CATHODE FOR COPPER ELECTROREFINING OR ELECTROWINNING

摘要

An improvement to a cathode used in an electrorefining or electrowinning of copper. The cathode has a solid copper head bar (2) with a horizontal groove (6) on its undersurface. The upper edge (9) of a stainless steel flat sheet has several holes (13) along its width and is vertically inserted into the groove. The stainless steel sheet is then mechanically attached to the coppe r head bar (2) by pressing the copper head bar against the stainless steel at the perforated points along the head bar. To increase the joint strength, th e stainless steel sheet may be welded to the copper head bar as its upper edge s at the underside of the head bar.
