A process for the production of gaseous diffusion grade UF₆ involving conversion of uranium ore concentrates to impure UF₆ which is purified by fractional distillation is presented. The use of a fluidized-bed technique is a desirable method for production of the crude green salt and methods of impurity removal were found. UF₆ can be produced by the fluorination of UF₄ in a fluidized bed reactor with excess fluorine at temperatures from 300 to 800⁰C. Fractional distillations were made of UF₆ from fluidized bed fluorinations, and operating conditions and product purifications are reported for the grades of feed materials tested. (J.R.D.)
