HYDROMETALLURGICAL PROCESSING OF URANIUM-BEARING RESIDUE MATERIALS TO UF$sub 4$
Technical Report
·
OSTI ID:4714592
The processes used to recover U values from residues generated during the manufacture of fuel cores are described. The various low-grade residues, after suitable feed preparation, are treated in a hydrometallurgical process to recover the U values as uranyl ammonium phosphate (UAP). The UAP after calcination to uranium pyrophosphate is returned to the production steam as a U concentrate. High-grade residues, including uranium pyrophosphate, are converted by an aqueous precipitation process to hydrated UF/sub 4/, which is dehydrated and used for the production of U metal. (auth)
