Dissertation

The hydrometallurgical production of zinc generates iron precipitation residues that are landfilled on a scale of several million tons annually. In a novel recycling process, the selective chlorination and separation of a number of valuable metals from the remaining iron matrix is investigated. In addition to studying the mechanisms of carbon-free chlorination reactions, the focus is on evaluating suitable chlorine-containing residues for combined recycling approaches.
