ABSTRACT:
A method and apparatus for separating magnetically susceptible particles from a mixture of magnetically susceptible particles and non-magnetic or less magnetically susceptible particles in which a stream containing the mixture in a fluidized condition is introduced under pressure or under gravity into one end of an arcuate separation channel having an inlet end and an outlet end and arcuate inner and outer walls and at least one connecting wall which confine the steam and constrain it to flow in a single unidirectional arcuate path along the channel in frictional contact with the inner and outer walls and with the connecting wall, the velocity of the stream and the frictional resistance to flow being such that the stream is subject to sufficient centrifugal force as it flows around the channel that there is produced in the channel a secondary circulation radially outwardly within the body of the stream and then radially inwardly, in which the stream during its passage around the channel is subjected to a radial magnetic field gradient so that the magnetic force and the secondary circulation cooperate to cause the magnetically susceptible particles to gravitate toward the magnet while moving through the channel, and in which the magnetically susceptible particles are removed from that radial side of the arcuate channel which is adjacent the magnet while the non-magnetic or less magnetically susceptible particles are removed from that radial side which is remote from the magnet.
