Description
Summary:	The rhenium concentration as well as Re(VII) and Mo(VI) separation from sulphuric and nitric–sulphuric acid solutions obtained after pyrometallurgical and nitric acid processing of rhenium-containing molybdenum concentrates were investigated on weak basic anion exchangers by means of sorption–desorption method and by IR-spectroscopy. The anion exchangers with porous and non-porous structure were synthesized on the basis of styrene and divinylbenzene using amines with cyclic radical. The resins AN-82-14G and AN-105-14G were used for the selective rhenium extraction from molybdenum-containing solutions. The complete rhenium recovery from nitric–sulphuric acid solutions was reached on porous anion exchangers AN-82-10P and AN-105-10P.
