  • Method and apparatus for separating magnetic material
    Patent number: 4902428
    Abstract: Separation of admixtures of particles, fluids or gases having different magnetic susceptiblities is effected by subjecting a moving stream of the mixture to simultaneous gravitational and magnetic forces in a manner such that relatively non-magnetic materials respond significantly to the gravitational force and relatively magnetic materials respond preferentially to the magnetic force.
