Abstract
In a method for sorting shredder residues of metal-containing wastes, in particular of vehicle bodies, where the shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction) and a system for implementing the method, (a) a crude-fiber fraction being generated during the processing of the shredder light fraction and the shredder heavy fraction in preliminary processes and a main process, by extracting at least a ferromagnetic fraction, a fraction containing nonferrous metals, a granulate fraction, and a sand fraction, and (b) the crude-fiber fraction being separated into a metal-containing dust fraction, a fiber fraction depleted in metals, and a metallic fraction in a refining process, using the successive process steps of metal-balling, dust removal, and density separation.
