Separation of rare earths by ionic liquid technology KU Leuven
The first part of this PhD thesis shows how ionic liquids can be employed as a green alternative to replace the conventional organic phase in solvent extraction processes of rare-earth elements. In a first approach, the selective leaching of rare earths from NdFeB magnets and their solvent extraction from a nitrate media is presented. More specifically, neodymium and dysprosium were separated from cobalt by extracting them to the ionic liquid ...
