Abstract
Separation apparatus and method for separating relatively magnetic particles from a stream of particulate material made up of relatively magnetic and relatively non-magnetic particles. A mixture of the magnetic and non-magnetic particles flows in a three-dimensional stream in a common path closely adjacent to the wall of a channel. A magnet producing a strong magnetic field force is located adjacent the wall of the chamber to produce a strong horizontal magnetic force and a vertical force which is less than that of gravity. The free fall of the particles adjacent the channel wall is interrupted in the vicinity of the magnet to cause the particles to move away from the wall. Thereafter, the magnetic particles move back towards the magnet whereas the non-magnetic particles are not drawn away from their diverted path.
