| Abstract: | The organic phase produced by extraction of a uranium leach liquor with Amberlite LA-2 in kerosene was stripped of uranium in laboratory tests with solutions of NaCl and H2SO4 or solutions of Na2SO4. It was found that NaCI-H2SO4 stripping reduced considerably the effectiveness of the solvent for subsequent extraction, whereas Na2SO4 stripped the uranium content without any deleterious effect. Optimum Na2SO4 concentration and pH for stripping were determined. Phase separation time and entrainment losses appear satisfactory. |
