Abstract RU 2033440 C1

FIELD: nonferrous metallurgy. SUBSTANCE: copper is extracted from solutions by sorption on amino-carboxylic amphoteric ionite at carboxylation degree 80-91% transferred to the intrasalt form. Proposed method ensures to increase process output and to get trade eluate (copper content above 30 g/l) from poor technological solutions containing copper at concentration 0.1-0.3 g/l. EFFECT: increased yield of copper. 4 tbl
