Apparatus for separating magnetic materials from nonmagnetic materials in a supply of mixed waste material, comprising an inclined rotary drum having loading means for introducing a continuous flow of mixed waste materials into the drum, means for simultaneously directing a stream of air at relatively high velocity through the drum to entrain and thereby remove light materials from the mixture therein out of the higher end thereof, means for rotating the drum to move heavy materials toward the lower end thereof, and magnetic means for selecting magnetic materials from the separated heavy materials and removing the magnetic materials separately from the drum.
