ABSTRACT:
The invention relates to a method and apparatus for electrolytic refining of copper and the production of copper wires for electrical purposes on a continual basis which produces round copper wires directly from impure copper anodes and to treat such wires in order to impart the desired characteristics as electrical conductors. The apparatus handles copper anodes of customary size refining them at normal current densities of less than 55 amps/foot.sup.2 onto starting wires of adequate tensile strength which is done continuously, the wire being provided to an electrolytic bath and, after withdrawal from the bath, the wires are finished by drawing and annealing.
