ABSTRACT:
In separating a mixture of solid material particles including non-magnetic electrically conductive metals into a light fraction and a heavy fraction, where the light fraction includes the non-magnetic particles, the mixture is directed into an upwardly extending airflow passageway from an inlet channel extending laterally from the passageway. The inlet channel is spaced between the inlet and outlet ends of the passageway. An alternating magnetic field is provided adjacent the entrance of the mixture into the airflow passageway for accelerating the particles in the desired direction. The mixture is fed through the inlet channel into the airflow passageway in layer form, preferably as a single layer. A main flow of air passes upwardly through the airflow passageway from the lower inlet end and develops a highly turbulent vortex-like airflow. The airflow, in combination with the magnetic field, effects separation of the light and heavy fractions of the material. A secondary flow of air is directed upwardly into the air flow passage in the region of the introduction of the mixture and accelerates the air flow and carries the light fraction upwardly to the outlet end of the passageway.
