    (54) Method and device for separating particulate matter


    (57) The invention relates to a method and a device for separating at least one particulate, electrically conductive, non-magnetic material which is included as a constituent or as constituents in a mixture, the separation being performed in a space permeable to magnetic waves, and the mixture in the space is subjected to an alternating magnetic field generated by a rotating element equipped with magnets. According to the invention, the particles are thrown up from the bottom of the space in a direction opposite to the direction of rotation of the magnet-equipped element and corresponding to a throwing angle α relative to the horizontal plane, 0 < α < 90, and the magnet-equipped element is disposed above the separation space.
    The device comprises a separation space (2, 3, 4) permeable to magnetic waves, means (5) for generating an alternating magnetic field, and feeding and discharging means. The means (5) is a rotating element equipped with magnets, and a throwing apparatus (11) is provided for throwing up the particles in the separation space in a direction opposite to the direction of rotation of the means (5), which is disposed above the separation space.
