RECOVERY OF URANIUM FROM AMINES BY THE HIGH NITRATE--WATER STRIPPING METHOD
>A method was developed for recovering uranyl nitrate from amines as a liquid rather than a solid concentrate. This procedure offers potential cost savings by simplifying the over-all uranium mill-- refinery flowsheet. The process involves treatment of the amine extract with calcium nitrate solution to convert the uranium in the solvent to the nitrate complex, stripping the uranium with water or dilute nitric acid, and recovering the nitrate from the solvent for recycle by contact with a lime slurry. Reagent costs for the stripping process were estimated at 4.9 cents per pound of U/sub 3/O/sub 8/. (auth)
