A feasible approach to selectively recover iron and rare earth elements (REEs) from red mud through acid leaching-coordination-solvent extraction was proposed. The leaching efficiencies of Fe, Al, Ti, Sc, La, Ce, Nd and Y can reach up to 95.9%, 82.1%, 68.3%, 93.3%, 82.3%, 96.9%, 98.3% and 95.6%, respectively, under the optimal condition in the leaching process. Aliquat 336 showed excellent extraction...
