FIELD: chemical technology. SUBSTANCE: copper regeneration from copper contained ammonium solution is making by solution flow passing through sequence of ion exchanging packing with weak base and carboxylic complexes. Packing are moving like counterflow range with respect to solution flow. As ion exchanging agent polyampholyte is using which includes weak base tetrazine complexes. Copper extraction from ion exchanging agent is making by ethylene-diamine tetra-acetate using which residual is displaced out by water. EFFECT: more effective copper regeneration processing. 4 tb, 1 dwg
