Goren, M B

A process for concentrating U values by acid leaching, solvent extraction, and stripping of the extractants is patented. The U ore is leached with aqueous sulfuric acid, and the U-containing leach liquor is contacted with a solution of water-insoluble organic amine solvent extractant. The resulting solution of U-loaded extractant is contacted with a stripping solution of a water- soluble inorganic sulfate. Na, K, Mg, or ammonium sulfates may be used, and the concentration should be at least 1 M in the stripping solution, which is at a temperature of 50 to 100 deg C. The stripping solution containing U is separated from the solution of U extractant, U is recovered from the stripping solution, and the solution may be recycled. The barren leach liquor may also be recycled in the leach circuit. (M.P.G.)
