METHOD TO PRODUCE HIGH-GRADE COPPER Russian patent published in 2012 - IPC C22B15/14 C25C1/12

Abstract RU 2455374 C2

FIELD: metallurgy.

SUBSTANCE: method involves electrolytic refining with dissolution of anode and transition of copper ions to the cathode. At that the electrolytic refining is accelerated by setting between the anode and the cathode of the lattice with negative potential, whose elements have protective insulation from the electrolyte.

EFFECT: reduced time of electrolytic refining, and reduction of specific electricity consumption.
