A wholly integral anode for electrolytic refining of metals
Abstract
Abstract Metallic copper or other metal, such as nickel, to be subjected to electrolytic refining is formed into a continuous slab strip of anode width and thickness. The strip is cut transversely of its width to form successive, rectangularly shaped, anode slab blanks, each having a pair of elongate members extending longitudinally of the strip at one set of corners of the blank. The so-formed blanks are passed individually through a bending operation, by which the elongate members of each blank are bent outwardly laterally of the blank and preferably within the plane thereof and intermediate the lengths of such members to form suspension lugs wholly integral with the remainder, i.e. slab body, of the blank, while being held preferably at the notched other set of corners of the blank from which the elongate members of the immediately preceeding blank were cut. The individual anodes, as articles of manufacture, have respective slab bodies, with wholly integral and upwardly and laterally outwardly projecting lugs at the upper corners thereof to serve as suspension hangers. These anodes are characterized by elongate notches at the lower corners of the respective slab bodies, such notches extending upwardly along the lateral margins of the slab bodies.
