Abstract

In a method and a system for sorting shredder residues of metal-containing wastes, in particular from vehicle body shells, shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction. The method and system provide for a raw-granulate fraction being produced during the sorting of the shredder light fraction and the shredder heavy fraction in preliminary processes and a main process, by separating out at least one ferromagnetic fraction, a nonferrous-metal fraction, a fiber fraction, and a sand fraction, and the raw-granulate fraction being split up in a refining process.
