A procedure of Dissolution in hot Uranium TETRAFLUORIDE impurity in a solution of nitric acid

摘要

Procedure for obtaining a solution of URANYL NITRATE by Dissolving tretrafluoruro impure Uranium in a solution of nitric acid and in the presence of an Aluminium Compound.It consists in introducing a First Stage 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.A second phase is introduced into Said suspension quantities of nitric acid and aluminium Compound, at least, enough to put the Uranium dissolved in solution in the first stage, keeping the suspension mixing at the same time.
