SOLVENT EXTRACTION OF URANIUM FROM REDUCTION SLAG SLURRY
The chemical feasibility of the Dapex and Amex solvent extraction processes for recovery of uranium from sulfuric acid leach slurry (20 wt.% solid) of magnesium reduction slag was demonstrated. Extraction isotherms show that only 3 to 4 theoretical stages are needed for good uranium recovery. Phase separation is rapid with virtually no emulsion if the mixing is controlled to disperse slurry in continuous solvent phase. In continuous countercurrent tests with the Dapex process using 5 extraction stages and 3 strip stages uranium recovery was 99.8%, and the product contained < 500 ppm of any one impurity. The solvent loss was less than 0.5 gal/1000 gal of slurry. The cost of chemicals for extraction, stripping, precipitation, and solvent loss was 13 cents per pound of uranium recovered. (auth)
