Abstract:
A cathode arrangement for an electrolytic bath for electrolytic production of pure copper, comprising:a current-supplying mounting rail, the mounting rail having a rectangular cross-section and having on its underside, which comprises oblique, non-rounded, grooveless surfaces tapered toward each other, two parallel flanges between the grooveless surfaces extending in the longitudinal direction of the mounting rail, the ends of the mounting rail contacting bus bars of the electrolytic bath; a cathode plate bonded to the mounting rail between the parallel flanges, the plate being bonded to the flanges by explosion welding, to form a full-surface metal bond, wherein the ends of the mounting rail that projects over the cathode plate have a flangeless design and oblique, non-rounded surfaces intersecting in the shape of a wedge on the underside.
