Abstract:
1. A method of using an apparatus having a separating zone for separating magnetic pieces of scrap-material of a first group from magnetic pieces of scrap-material of a second group, the method comprising the steps of: transporting via a conveyor a mixture of said pieces of scrap-material from the first group and from the second group to the separating zone; subjecting at the separating zone the mixture of pieces of scrap material to a magnetic field; and supporting at the separation zone the conveyor by a drum around which the conveyor passes at a predefined speed so as to impart on the mixture of magnetic pieces of scrap-material a pre-defined horizontal velocity at which said pieces are released from the conveyor at separating zone so as to subject the pieces of scrap-material to forces induced by the magnetic field and to gravitational forces; and wherein the first group of material concerns ferrous scrap with a bulk-density of less than 900 kg/m
