Refuse, particularly of the household type, is sorted according to density by the following consecutive operations: Sifting the refuse; comminuting the oversize obtained; separating the comminuted material by a gas stream into light and heavy material fractions; separating the heavy material fraction by a liquid stream into two fractions of different density; and separating the two fractions of different density into basic components.
