METHOD OF EXTRACTING RHENIUM FROM URANIUM-CONTAINING SOLUTIONS Russian patent published in 2014 - IPC C22B61/00 C22B3/24 

Abstract RU 2523892 C2

FIELD: chemistry.

SUBSTANCE: invention relates to sorption hydrometallurgy of uranium and rhenium and can be used to extract rhenium from solutions and pulp. The method of extracting rhenium from uranium-containing solutions includes sorption of rhenium on anions. Before sorption, fulvic acids are added to the solution until concentration thereof in the solution reaches 25-300 mg/l. Rhenium sorption is carried out at solution pH 2.8-3.5. Sorption is carried out on weakly basic and strongly basic anionites.

EFFECT: improved sorption/desorption properties, high cost/performance ratio of the sorption sorption/desorption process of extracting rhenium from a uranium-containing solution.
