A procedure for the use of uranium and rare-earth content in the impure Uranium TETRAFLUORIDE from the Recovery of uranium from Phosphoric Acid

摘要

Procedure for the use of uranium and rare-earth content in the impure Uranium TETRAFLUORIDE, The recovery of uranium from Phosphoric acid.It includes the following steps: First, we introduce insufficient quantities of nitric acid and aluminium compound in the prepared suspension of uranium TETRAFLUORIDE impure, keeping stirring the suspension during a time of at least 0.5 hours; Second, introduce the C Quantities of nitric acid and aluminium Compound, at least enough,The suspension of uranium TETRAFLUORIDE impure, put the Uranium dissolved in solution in the first stage, at the same time maintaining the suspension while stirring; and finally, extract the URANYL NITRATE obtained, putting in contact with the Solvent and the suspension Xtraccion containing Phosphoric Ester.
