PREPARATION OF HIGH PURITY UF$sub 4$

Patent ·
OSTI ID:4822337

A process is given for preparing highly pure uranous tetrafluoride from an impure uranium laden solvent extraction process strip solution which is at least 8 M in mineral acid. The process coniprises treating said strip solution with a reducing agent thereby reducing the uranium in said strip solution to the +4 oxidation state, contacting the strip solution with an extractant phase comprising about l0 to 70% of tributyl phosphate in an organic solvent-diluent selected from the group consisting of benzene, ethyl-benzene, chlorobenzene, toluene, xylene, kerosene, and c-arbon tetrachloride to extract the uranium therein, treating the extract phase with an aqueous fluoride solution to precipitate uranous tetrafluoride therefrom, and separating the uranous tetrafluoride from the phases.
