FIELD: metallurgy.
SUBSTANCE: method for extracting rhenium from solutions involves sorption using weakly basic anionite as a sorbent. At the same time, sorption of rhenium is carried out from solutions with a pH of 3.6-7, and the anion is washed from iron with a solution of sulfuric acid with a concentration of 3-15 g/l (pH 1.5-15).
EFFECT: increasing the efficiency of rhenium extraction from neutral and close to neutral leaching solutions, while increasing the life of anionite and reducing the consumption of anionite, increasing its sorption load, and reducing the consumption of sulfuric acid.
