A semicontinuous process was developed for dissolving the solid residues that are produced in the Ca-reduction process for converting plutonium fluoride to plutonium metal. The slag and crucible residues are charged to a column-type dissolver and are there exposed to a flowing solution of hot nitric acid followed by a nitric acid-aluminum nitrate solution. The resultant solution is suitable as feed to an ion exchange process for recovering Pu. A method was demonstrated for recovering Pu from the dissolver solution by anion exchange in agitated beds of resin. The use of agitated beds of resin eliminates the need for filtering the feed.
