  • Separation and recovery of critical metal ions using ionic

    Separation and purification of critical metal ions such as rareearth elements REEs, scandium and niobium from their minerals is difficult and often determines if extraction is economically and environmentally feasible. Solvent extraction is a commonly used metalion separation process, usually favored because of its simplicity, speed and wide scope, which is why it is often employed for
