摘要： Method of obtaining and separating valuable metallic elements from low-grade uranium ores and radioactive liquid wastes, as used herein, consists in feeding a liquid-solid suspension into the membrane system with the contactor with helical flow, whereas the solid is a known sorbent, preferably activated carbon or complexing agent, preferably soluble polymer, specifically polyacrylic acid. The use of activated carbon as a sorbent, concentration from c = 0.1 g/dcm 3 to c = 0.8 g/dcm 3 , and of the contactor with helical flow, at rotor rate from 800 rpm to 1,200 rpm will mean a virtual absence of the fouling phenomenon and the value of the retention coefficient equal to 60%. On the other hand, when a soluble polymer, specifically polyacrylic acid, is used as a complexing agent, the method as used herein consists in that at the concentration of polyacrylic acid from c = 0.2 g/dcm 2 to c = 0.2 g/dcm 2 , proportion c me /c polymer = 1.4, rotor rate of 1,800 rpm to 2,200 rpm, will mean a virtual absence of the fouling phenomenon and the value of the retention index equal to 98%. For the two options, the time necessary for binding the metallic ion equilibrium content was 6 times shorter compared with the prior art.

摘要： A process for facilitating the removal of impurities e.g. radionuclides, such as uranium and thorium, and/or one or more of their radionuclide daughters, from titaniferous material includes contacting the titaniferous material with one or more reagents at an elevated temperature selected to enhance the accessibility of at least one of the radionuclide daughters in the titaniferous material. The reagent(s) may be a glass forming reagent and is selected to form a phase at the elevated temperature which disperses onto the surfaces of the titaniferous material and incorporates the radionuclides and one or more radionuclide daughters. The titaniferous material may be, e.g., ilmenite, reduced ilmenite, altered ilmenite or synthetic rutile.

摘要： A process for selectively separating a metallic constituent from other metals and other materials accompanying the metallic constituent in a mixture is described. The process comprises the step of providing the mixture in an aqueous solution such that the metallic constituent forms a complex anion in the solution. One or more of the other metals forms a cation or a complex cation in the solution. Another step includes contacting the solution with one or more additives to form layered double hydroxide (LDH) material in situ such that the complex anion is intercalated within interlayers of the LDH material and wherein one or more of the other metals are incorporated into the LDH material's crystal structure or matrix. Another step involves the addition of an LDH to an aqueous solution. The process involves selectively recovering the metallic constituent from the interlayer of the LDH by subjecting the LDH to a recovery treatment step(s) and as required, methods to modify the LDH to facilitate metal separation and recovery or contaminant stabilisation.

摘要： A method is disclosed for reducing the volume of a radioactive composition by separating a radioactive first component from a second component of the radioactive composition. The method includes directing the radioactive composition into a reaction zone. The reaction zone includes a molten bath, wherein oxidation of a component of the radioactive composition in the molten bath will cause separation of the radioactive first component from the second component. An oxidizing agent is directed into the molten bath, which oxidizes a component of the radioactive composition, whereby the radioactive first component is separated from the second component. The net volume of the radioactive composition is thereby reduced.
