METHOD OF EXTRACTING URANIUM FROM SODIUM FLUORIDE SORBENT Russian patent published in 2011 - IPC C01G43/06

Abstract RU 2422366 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in processing wastes containing uranium fluorides. Sodium fluoride sorbent which contains uranium (V) is treated with water vapour at temperature 100-250°C. Uranium is then extracted through fluorination at temperature not higher than 400°C.

EFFECT: invention lowers fluorine consumption and prevents sorbent agglomeration.
