SELECTIVE EXTRACTION OF RHENIUM (VII) IONS FROM WATER SOLUTIONS OF METAL CATIONS

摘要

FIELD: metallurgy.;SUBSTANCE: method for extraction of rhenium (VII) from the solutions containing non-ferrous metals involves preparation of solution and sorption of rhenium (VII). Sorption is performed from sulphate solutions containing cations of non-ferrous metals of nickel, cobalt or copper. The process is performed at mixing with AM-2"б" anionite or with absorbent bone coal at pH value of solutions, which is less than pH value of hydrolytic deposition of cations of non-ferrous metals.;EFFECT: increasing efficiency of selective extraction of rhenium from solutions of non-ferrous metals.;4 dwg, 3 tbl, 3 ex
