ABSTRACT:
There is disclosed a process and apparatus for recovering metallic uranium from scrap containing metallic uranium by introducing such metallic uranium scrap into a bath containing, in molten form, at least one member selected from the group consisting of BaF.sub.2, CaF.sub.2, MgF.sub.2, LiF, YF.sub.3, trifluorides of lanthanides and mixtures thereof, preferably with such member constituting at least 75 mole percent of the bath at a temperature above the melting point or uranium and under an inert atmosphere and casting the purified molten metallic uranium. The bath of molten salt preferably includes means for improving contact between the molten metallic uranium scrap and the molten salt during passage of the molten uranium through the bath of molten salt.
