FIELD: chemistry.
SUBSTANCE: invention can be used in rhenium hydrometallurgy. Rhenium is gathered from the starting solution on a weakly basic anionite on a styrene matrix. The rhenium-saturated anionite is washed with water and then treated with an ammonium salt solution with addition of ammonia solution until achieving pH 6.9 - 7.6. The anionite is then removed from the solution, washed with water once more and rhenium is desorbed with ammonia solution followed by extraction of rhenium in form of ammonium perrhenate, which is the end product.
EFFECT: invention increases the degree of purifying rhenium from molybdenum on non-porous and macroporous anionites.
