Non-aqueous solvent extraction of metal ions KU Leuven
The transition towards a climate-neutral, eco-friendly economy critically depends on the availability of a wide variety of high-purity metals (e.g. cobalt). Solvent extraction (liquid-liquid extraction) is an important unit process used by the metallurgical industry for the recovery, separation and purification of metal salts. Solvent extraction is based on distribution of metal ions between two immiscible liquid phases, often an aqueous and ...
