FIELD: metallurgy.
SUBSTANCE: method of zinc extraction from water solutions by tributyl phosphate includes extractant and solution contact, mixture mixing, settling-out and phases separation. Extraction is performed from the water solution with concentration 3 n. HCl, 240 g/dm3 NaCl. Tributyl phosphate is added by portions at 20°C.
EFFECT: invention increases efficiency of zinc extraction from water solutions, reduces extractant consumption.
