ABSTRACT:
A method is provided for cleaning depleted uranium and its associated radioactivity from target sands, for reusing many of the reactants used in the cleaning, and for recovering the depleted uranium content as uranyl nitrate. The method involves roasting and tumbling target sands with molten nitrate mixtures, followed by aqueous extraction to remove the nitrates, then nitric acid extraction to remove uranium oxides as uranyl nitrates which can be solvent extracted into organic phases.
