Document Type and Number:
Japanese Patent JPS5930650
Kind Code:
B2
Abstract:
A method of recovering uranium from an aqueous calcium fluoride slurry is disclosed. The pH of the slurry is first adjusted to between 2 and 3 using an acid such as nitric acid. The supernatant fluid is then separated from the remainder of the slurry, as for example, by permitting the slurry to settle for several days. Finally, the uranium is removed from the supernatant fluid which can be accomplished by using an ion exchange column or by precipitation with water glass. The steps of the invention can be repeated on the remaining slurry to reduce the uranium level as desired.
