FIELD: electrolytic refining of metals, metallurgy, separation of lead from bismuth. SUBSTANCE: process of refining of bismuth lead includes electrolysis in fluorosilicate solution. In correspondence with invention anodes are replaced in turn in process of electrolysis every 24-48 h. EFFECT: increased degree of refining of lead from bismuth, prolonged service life of anodes, diminished thickness of layer of anode sludge thanks to prevention of contamination of cathode residue with mechanical impurities. 1 tbl |
