METHOD OF PROCESSING URANIUM FLUORIDE-CONTAINING WASTES Russian patent published in 2011 - IPC C01G43/00 G21F9/28

Abstract RU 2421402 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in processing sublimate production wastes. Solid uranium fluoride-containing wastes are treated with sulphuric acid to obtain a sulphate-fluoride solution. Aluminium sulphate is then added to the obtained solution in ratio Al:F = 1:6 and then taken for sorption purification from Mo and W on a titanium oxide-based sorbent containing 5 mol % zirconium oxide, and then undergoes extraction purification from impurities.

EFFECT: invention enables to obtain high-purity uranium-containing material.
