Abstract

An apparatus for separating a nonmagnetic conductive material from a nonmagnetic nonconductive material. The separation apparatus comprises a drum arranged in a tilted fashion and rotating in one direction about the longitudinal central axis and a chute for throwing a material being separated into the drum from the upper opening thereof. The material supplied through the chute into the drum is agitated by rotation of the drum, and the nonmagnetic conductive material of the material thus supplied into the drum receives an electromagnetic force produced by a magnetic field moving in a direction opposite to the direction of rotation of the drum, so as to be separated from the nonmagnetic nonconductive material. In order to increase the agitation effect for the material supplied into the drum, the chute is biased from the center of the upper opening of the drum to one side of the center depending on the rotational direction of the drum, and shoulder portions are provided on the inner peripheral wall of the drum.
