METHOD OF PROCESSING URANIUM HEXAFLUORIDE Russian patent published in 2013 - IPC C01G43/01 C01G43/06

Abstract RU 2489357 C2

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering of inorganic substances and can be used to process depleted uranium hexafluoride. The method of processing uranium hexafluoride involves dissolving uranium hexafluoride in water to obtain a uranyl fluoride solution; the obtained solution is treated with ammonia water to obtain solid ammonium polyuranate and ammonium fluoride solution; the solid fraction is filtered out and annealed at temperature of 450-600°C to thiuram octaoxide and after filtration, the solution is evaporated to obtain solid ammonium fluoride.

EFFECT: invention provides an efficient industrial method of processing uranium hexafluoride to obtain commercial-grade versions of uranium and a fluorine-containing product.
