METHOD OF MANUFACTURING COPPER PHOSPHORUS-CONTAINING ELECTROLYTE ANODES Russian patent published in 1998 - IPC

FIELD: nonferrous metallurgy. SUBSTANCE: copper phosphorus-containing anodes are manufactured from copper wastes with fraction +0.25 mm which are processed by electrolysis in electrolyte composed of, g/l: cupric sulfate pentahydrate, 200-250; sulfuric acid, 30-50; phosphorus oxo-anion-containing inorganic compound, 1-8 (depending of nature of compound); phosphorus-containing protein compound, 0.1-3 (depending of nature of compound). Copper wastes may be electroplating, metallurgic, and processing production wastes, including those with C-P-type hardener added containing 9-12 wt % phosphorus at weight ratio 100: 1. EFFECT: reduced power consumption and increased copper recovery. 3 cl, 2 tbl, 3 ex
