Ionic liquid-based aqueous biphasic systems for rare-earth metal recovery KU Leuven
Rare-earth elements have high economic importance and are often found in high-tech applications. Solvent extraction is a crucial step and usually a predominant technology for the separation of metal ions, to produce pure compounds or metals from mineral ores or secondary resources (end-of-life products). Ionic liquids (ILs) have been widely studied in solvent extraction system as solvent or extractant for metal separations. However, the high ...
