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. The separator also includes a material feeder, a discharge channel for collecting nonmagnetic product mounted on the opposite side of the common tangential plane array, means for collecting magnetic product, and liquid supply channel separated from the feeder by a divider extending into the separation chamber. To enhance separation, a separate stream of clean liquid is introduced into the separation chamber through the liquid supply channel, so that the liquid stream encounters the stream of material undergoing separation.
