METHOD OF OBTAINING URANYL NITRATE Russian patent published in 2015 - IPC C01G43/00 C01B21/48

Abstract RU 2563480 C2

FIELD: chemistry.

SUBSTANCE: invention relates to technology of processing chemical concentrates of natural uranium. Method of obtaining uranyl nitrate includes processing of uranium compounds, such as: uranium oxides, sodium polyuranates, ammonium polyuranates or uranium peroxide with water solution of ammonium nitrate, and sintering obtained mixtures in temperature interval 200-350°C.

EFFECT: invention provides increase of uranyl nitrate output and reduction of process explosion hazard.
