Abstract
1,222,807. Ammonium diuranate. WESTINGHOUSE ELECTRIC CORP. 28 March, 1969 [4 April, 1968; 4 March, 1969], No. 16331/69. Heading C1A. Uranium is recovered as ammonium diuranate by adding to an aqueous solution containing uranyl fluoride and HF sufficient aqueous ammonium hydroxide to bring the pH of the mixture to 6À1 Œ 0.2 and when the formation of ammonium fluoride is complete then adding sufficient aqueous ammonium hydroxide of a normality less than 3N to precipitate ammonium diuranate. When the solution contains about 4 molcules of HF per mole of uranyl ion the ammonium hydroxide in the first step is added in an amount such that 3À5 moles of NH 4 OH are present in the mixture per mole of UO 2 <SP>2+</SP>. In the second addition 3 to 5 mols. of NH 4 OH per mol. UO 2 F 2 may be added.
