Ion exchange concentration of uranium
WebConversion to uranium metal is accomplished through the Ames process, in which UF 4 is reduced with magnesium (Mg) at temperatures exceeding 1,300° C (2,375° F). (In an often-used modification of the Ames process, calcium metal is substituted for magnesium.) WebVandaag · Uranium and molybdenum are important strategic elements. The production of 99 Mo and the hydrometallurgical process of uranium ore face difficult problems of separation of uranium and molybdenum. In this study, the four phenanthroline diamide ligands were synthesized, and extraction and stripping experiments were performed …
