Abstract: Thermodynamics of separation of praseodymium and neodymium employing liquid lowmelting metals and alloys is considered. Pr/Nd separation factors on liquid Ga, In, Bi, and GaIn eutectic were calculated from the thermodynamic data. The obtained results are compared with the literature data on experimentally determined separation factors on “traditional†liquid metals: Bi, Zn, and Cd. It is shown that onestage selective extraction of praseodymium or neodymium from the mixture using any of the mentioned metals is not possible. In the separation process of lanthanides from minor actinides using a chloride molten salt–liquid metal system, cerium group lanthanide fission products will be accumulated in the salt phase.
