PROCEDURE FOR PROCESSING URANIUM-MOLYBDENUM COMPOSITION Russian patent published in 2010 - IPC G21C19/44

Abstract RU 2395857 C1

FIELD: metallurgy.

SUBSTANCE: procedure for processing uranium-molybdenum composition consists in oxidising uranium-molybdenum composition at temperature 750-850°C, in dissolving composition in 2-3 molar solution of alkali at temperature of boiling, in separating solution from solid residue by decantation, in dissolving solid residue in 4-6 molar nitric acid at boiling temperature, in peroxide sedimentation of uranium from solution and in baking settled uranium peroxide at temperature 750-850°C.

EFFECT: raised degree of uranium extraction at processing uranium-molybdenum composition.
