| Abstract Scope |
Developing efficient and viable processes for separation of critical metals is essential to meet the increasing demand. Rare earth elements (REE:s) are identified by the EU as critical resources, and moreover they are difficult to separate due to their similar properties. Extraction chromatography is a powerful method suitable for difficult, high-purity separations, which could form part of a separation process for recovery of REE:s from various sources. In the present work, separation of REE:s from aqueous leach solutions of apatite is investigated using physically immobilized extractants. By means of reverse-phase columns, reversibly functionalized by acidic organophosphorus compounds, the metals are separated by elution with nitric acid solution. |
