METHOD OF REFINING URANIUM
A method is given for refining impure uranium produced by electrolysis or by other reduction processes. In this method, impure uranium is melted in a fused salt bath containing an alkali metal halide and an alkaline earth metal halide, and after a suitable interval, molten purified uranium is allowed to coalesce and then is removed from the bath. A particularly suitable bath is one contaiing KHF/sub 2/ and BaCl/sub 2/. The purifying action probably resides in a combination of vaporization and dissolution and/or retention of impurities in the salt bath. In this way, uranium may be purified from oxide and salt impurities and metals such as sodium, and steps such as crushing, washing, grinding sin- tering, etc., may be eliminated. (D. L.C.)
