SEPARATION OF URANIUM PEROXIDE FROM MIXTURES

Patent ·
OSTI ID:4194175
S>A process is presented for extracting U from an aqueous uranyl sulfate solution. The process removes ions which interfere with precipitation of peroxide from the sulfate solution. The U/sup 4+/ is oxidized to U/supSTA 6+/ by H/sub 2/O/sub 2/, and the s olution heated to 90 to 95 deg C. Over a two-hour period CaCO/sub 3/ powder is added to bring the pH from 1.0 up to 3.7 to precipitate Fe. In other examples, procedures for removing B, Cu, Co, Cr, Mo, Mn, Ni, Cd, Li, Hg, La, V, Ga, and Sm are given. (T.R.H.)
