Extraction of light, medium and heavy rare-earth elements using synergist extractants developed from ionic liquid and conventional extractants

This study focuses on the extraction of rare-earth elements (REE) using eight newly formulated synergist extractants and the performance was compared with that using the conventional extractants. Extraction was conducted on selected REE namely praseodymium (Pr), gadolinium (Gd) and dysprosium (Dy) r...
