Patent
·
OSTI ID:5676105
This patent describes a method of producing uranyl peroxide (UF/sub 4/ . 2H/sub 2/O) from uranium-bearing metal pieces comprising: dissolving the uranium-bearing metal pieces in a first aqueous solution containing nitric acid and at least 0.5% but no more than 2.0% fluoboric acid to provide a second aqueous solution which includes uranyl ions (UO/sub 2//sup +2/) and nitric and fluoboric acids; adding hydrogen peroxide to the second aqueous solution to precipitate uranyl peroxide out of the second solution and provide a third aqueous solution containing nitric and fluoboric acid; and separating the uranyl peroxide from the third aqueous solution.
