| Abstract: | In the present study, the use of 5% Aliquat-336/kerosene was evaluated in the liquid–liquid extraction of Uranium(VI) and some impurities of Thorium(IV) and rare earth elements (REEs(III)). Experiments were carried out to determine the factors affecting U(VI) and some impurities of Th(IV) and REEs(III) extraction. McCabe–Thiele diagram was constructed to define the theoretical stages for extraction mixer settler process. The effect of stripping factors from the loaded extractant was also tested. Uranium cake was finally obtained from the strip solution and a workable flow sheet was then formulated. |
