Aprocess for recovering a total REEs using di-2-ethylhexyl phosphoric acid(D2EHPA)in kerosene from the sulfate solution of calcareous shale ore material of Wadi Nasib area was performed. Chemical composition of the ore material revealed the presence of 0.2% of U, 0.18% of REEs as well as 2.7% of Cu as the elements of interest. The pregnant sulfate solution has been already prepared by agitation leaching of 250g of the fine ground ore sample using 200g/L of H2SO4 solution at S/L ratio of 1/4 and string for 4 h at 80ºC. The latter was found assaying 400 mg/L of REEs with achieved leaching efficiency of 96%. REEs extraction efficiency was achieved using 1M of D2EHPA. The stripping process of REEs from the loaded organic phase was conducted using 0.5M H2SO4 solution.
