THE PREPARATION OF METAL GRADE UF$sub 4$ FROM SCRAP BY THE WINLO PROCESS

Technical Report ·
OSTI ID:4231565
An amine extraction flowsheet has been developed in the laboratory which will purify low-grade MgF/sub 2/ -type scrap sufficiently for precipitation of metal-grade UF/sub 4/ by the Winlo aqueous precipitation process. An alternative scrap treatment process, the currently used UAP precipitation, was found to give sufficient purification so that the UAP could be dissolved in hydrochloric acid and metal-grade UF/sub 4/ precipitated from this solution by the Winlo process. Several of the high-grade blackoxide scrap streams were found to be sufficiently pure to be amenable to a hydrochloric acid dissolutionaqueous UF/sub 4/ precipitation process without prior purification. Scale-up of the aqueous UF/sub 4/ precipitation process from beaker scale to pilot scale has been successfully accomplished. Decontamination factors for various elements during precipitation were determined. (auth)
