The criteria to be used in determining whether solvent extraction is applicable to a given feed material, and if so, which solvent, what type of equipment, and what operating conditions should be employed are discussed. The general advantages and disadvantages of solvent extraction are outlined. The efficiency of di(2-ethylhexyl) phosphoric acid (EHPA) in recovering uranium was examined. A flowsheet for the recovery of uranium from a sulfuric acid leach liquor with a O.lM EHPA-O.lM TBP solution in kerosene is shown. Amines were found to have several definite advantages over EHPA as uranium extractants. The extraction of uranium by amines is analogous to the adsorption of uranium by anion exchange resins. A flowshest for the recovery of uranium and molybdenum from leach liquor using an amine in kerosene is givsn. (M.C.G.)
