Abstract Scope Rare earth metals and their compounds are key materials for different high technologies. To guarantee a continuous supply of these critical metals novel recycling processes need to be introduced in the future. The goal of our studies is to develop and implement processes for the recovery of rare earth metals, especially lanthanum and cerium, from spent FCC catalysts. The matrix of FCC catalysts contains alumina as main component and the development of a hydrometallurgical recycling procedure using precipitation and solvent extraction steps after an acid leaching of the material is required. The talk covers selected aspects of leaching with various mineral acids, precipitation with different precipitation agents as well as solvent extraction with neutral and acid phosphorus extractants and their mixtures. An outlook will be given to novel selective extractants and their sustainable synthesis routes. The studies are involved in the effort of Vietnamese refineries to decrease the amount of waste and to solve environmental problems.
