Abstract
The present work investigates the separation of two rare-earth element s, samarium and gadolinium, by solvent extraction. A comparative study , at batch and continuous scale, has been carried out with phosphoric acid (D2EHPA), phosphonic acid (IONQUEST 801) and a phosphinic acid (C YANEX 272) extractants. Efficient Samarium-Gadolinium separation has b een achieved with the phosphoric and the phosphonic extractants.
