Abstract

In this research work the chloride and sulfate ions have been decreased in the LEACH LIQUORs using Hydrofluoric acid 40% and commercial lead nitrate prepared by sea water in sulfuric Acid media. As the result of chloride ion deduction in LEACH LIQUOR the relative competition of uranium with other elements to transfer to normal TBP structure as solvent extracting of uranium will be also reduced. It is investigated that in nitrated media of leach solution more uranium will transfer to TBP phase. Then reextraction and analysis were done by colorimetric method of developing uranylferrocyanide complex in 540nm as the fixed wavelength. In this study the interfering effect of fluoride ion is also considered and evaluated by the above mentioned complex. Comparing the results of uranium analysis obtained by ICP technique show that the effect of fluoride as an interfering ion is more serious in single stage than multistage of chloride precipitation process. Promising signs of analytical results have led us to be familiar with the high purity YELLOW CAKE production Know-How as well. This separation procedure is well organized and well suited to apply on the uranium resources called salted arches shaped. Besides, in this study the successful quantitative Separation of better than 99% of molybdenum from uranium is also considered
