Abstract This paper describes the extraction of uranium from raffinate phosphoric acid purified using aliquatR336 in kerosene as a selective extracting agent of uranium, Several factors were studied for the maximum extraction of uranium. mainly aliquatR336 concentration, shaking time, aqueous/organic phase ratio, the diluents effect and temperature on the extraction, Effect of different stripping agents were investigated , High uranium extraction yields 98.4% were obtained ,The uranium is finally converted to a high purity using precipitation with hydrogen peroxide, Finally a technological flow sheet is elucidated on the basis of the obtained results.
Keywords Uranyl Peroxide; Phosphoric Acid; Organic Solvents; Aliquatr336.
