A method is disclosed for separating fractions of incinerated refuse with a high recuperation yield without requiring special equipment. A first portion of the separation process may be applied to either an initially dry or an initially wet refuse. The refuse is at first screened to a median size. The oversized fraction is crushed and shredded and the non-magnetic fraction separated therefrom is sent commonly to a grinding-rolling mill which also receives the undersize fraction. The undersize fraction downstream of the grinding mill is further treated by a wet separating process, the method achieving separation of ferrous and nonferrous metals, of glasses and silicates, and of magnetic slags.
