A method and system are for sorting shredder residues of metal-containing wastes, in particular of body shells Shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction (shredder heavy fraction). During the sorting of the shredder light fraction and the shredder heavy fraction in preliminary processes and a main process, a crude-sand fraction is produced by separating out at least a ferromagnetic fraction, a fraction containing nonferrous metals, a fiber fraction, and a granulate fraction. In a refining process, the crude-sand fraction is separated into a residual fraction rich in organics, a dust fraction containing heavy metals, a sand fraction depleted in organics and metals, and a metallic fraction, using the sequential process steps of density separation and metal separation.
