METHOD OF COPPER RECOVERY BY PYROMETALLURGICAL TECHNIQUE Russian patent published in 1998 - IPC

Abstract RU 2116366 C1

FIELD: processing of copper-containing technogenic wastes with recovery of blister copper. SUBSTANCE: pyrometallurgical method includes melting of copper scale and anode sludge introduced with excess with respect to stoichiometric ratio to each other in definite periods of process cycle. The method may be used in continuous cycle with periodic discharge of qualitative blister copper in the form of ingot with degree of copper recovery from technogenic materials up to 99%. EFFECT: increased degree of copper recovery without increased energy expenditures. 3 cl, 1 tbl
