Extracting Uranium From Ore

Check this site for mobile hairdresser insurance The first stage of this process is to dissolve the yellow cake in nitric acid; solvent extraction using tributyl phosphate in a hydrocaron solution extracts the uranium from the various impurities and then the extract is washed with dilute nitric acid to produce uranyl nitrate in a very pure form. This is then heated to a high temperature to produce uranium trioxide; hydrogen is introduced to reduce this to the dioxide, the extra oxygen molecule being taken by the hydrogen to form water; and then this UO2 is treated with hydrogen fluoride at a high temperature to create uranium tetrafluoride and water. This is then heated yet again, this time with magnesium to form molten metallic magnesium together with magnesium fluoride slag. Phew! Are you still with me so far?
