Refuse scrap from incinerated refuse or nonincinerated refuse is dried and precleaned to a metal content in excess of 70% and is then comminuted and abraded in a hammer shredder with the comminuted material being subjected to air separation and magnetic separation to yield a metal product containing at least 90% metal and with a density of at least 1 ton per m.sup.3 for direct use as any other iron scrap in a steel-making plant.
