Possible methods of beneficiating Saskatchewan pegmatites for uranium recovery at competitive cost were investigated. The work has involved a study of several acid-leach techniques, a search for a suitable combination of flotation reagents, and the removal of uranium from sulfate-leach liquors by liquid-liquid extraction. The results of stagnant leach, rolling leach, acid cure leach, and percolation leach are tabulated. The techniques of acid-cure and percolation leaching are described. Suitable reagents were found for flotation of Charlebois Lake and Bleasdell Lake pegmatite. The results of pilot plant flotation tests are given. The leaching of flotation concentrates requires more sulfuric acid and more oxidizing reagent. Amberlite LA-l can be used satisfactorily in the liquid-liquid extraction of uranium from sulfate leach liquors. (J.S.R.)
