  • Methods and apparatus for making continuous magnetic separations
    Patent number: 5568869
    Abstract: Magnetic separations are made by feeding material to a magnetic separator having elongated ferromagnetic bodies that are disposed parallel to each other with spaces therebetween, the bodies being disposed at an angle to the magnetic field direction. The magnetic particles are deflected away, while the nonmagnetic particles pass through the spaces between the ferromagnetic bodies. In one embodiment, the separator includes a magnetic circuit including an array of elongated ferromagnetic bodies, parallel to each other with spaces therebetween, and on the same side of a common tangential plane that is positioned substantially perpendicular to the direction of the field created by the magnetic system and at an acute angle to the direction of particle feed towards the ferromagnetic bodies.
