The solution is then fed to IX SX where impurities are eliminated and uranium solution is concentrated.
2019-10-17often reduces the impurities content that have to be removed in the downstream processes. In this concern the obtained precipitate cake was contacted with sodium carbonate solution 30 gL for 4 hours at reaction temperature of 90 oC.
Uranium Processing. Uranium Milling . which remain solid. The uranium-rich solution is then purified through a solvent extraction process and solidified through chemical precipitation. . the uranium is separated from impurities through a series of chemical processes including digestion solvent extraction and denitration.
The uranium concentration in acid leach solution is high for example 800-900 mgL U SX is more preferable than IX in term of costs Tonder and Kote 2007 Ivanova et al. 2009.
In either case the uranium compound is removed from the original solution leaving many impurities behind. By repeating the ion exchange or solvent extraction process it is possible to obtain a very pure uranium product.
