A device for separating a mixture material into a magnetic material, a nonmagnetic conductive material and a nonmagnetic nonconductive material. The device comprises a drum revolving in one direction about a longitudinal central axis thereof. The magnetic material of the mixture material thrown into the drum is attracted to the inner peripheral surface of the drum by the magnetism of a magnetic field surrounding the drum and rotating in a reverse direction to a direction of rotation of the drum, and released from the inner peripheral surface of the drum in a predetermined rotational region in the drum, thereby being received on a receiving member. The nonmagnetic nonconductive material is directed in the direction of rotation of the drum along the inner peripheral surface of the drum, and the nonmagnetic conductive material is directed in a reverse direction to the direction of rotation of the drum by the electromagnetic force of the rotating magnetic field.
