>Laboratory data and a process chemical flowsheet are given for the recovery of uranium from aqueous sulfate solutions by solvent extraction with tributyl phosphate. Uranium may be recovered from solutions containing as much as 2.5 moles of sulfate per mole of urantum by adding sufficient nitrate-ion salting strength, in the form of aluminum nitrate and nitric acid, to overcome the complexing effect of the sulfate. The use of 15 moles of nitrate per mole of sulfate permitted essentially complete extraction of uranium in about 2.5 theoretical stages. Gross BETA and gross gamma decontamination factors of 1 x 10/sup 5/ and 2.43 x lO/sup 3/, respectively, were obtained during processing of the uranyl sulfate core of the Raleigh Research Reactor; uranium losses were 0.008%.
