• Description:
  A solvent-extraction system employing selective stripping of a preloaded organic phase was investigated for recovering sm2o3 from a light-group rare-earth mixture. The samarium concentrated in the organic phase, and a >99-pct-pure samarium oxide product was obtained at 76-pct recovery in a 20-stage operation using di(2- ethylhexyl) phosphoric acid (ehpa) as the organic phase. The stripping agent was a 1.5-Pct hydrochloric acid solution containing 200 g nh4cl per liter. [Description provided by NIOSH]
