Separation of rare earths by non-aqueous solvent extraction KU Leuven
Solvent extraction is widely used for the separation of mixtures of rare earths on an industrial scale. However, these separation processes are not very efficient so that many extraction stages are required to produce pure rare earths. In this project, we develop a new approach to separation of rare earths: non-aqueous solvent extraction with two immiscible organic phases. Non-aqueous solvent extraction offers some advantages compared to ...
