Magnetic separation

Image Number 4 for United States Patent #4214984.

A process is disclosed for separating a relatively more magnetic material from a relatively less magnetic material comprising passing the material being processed through a plurality of regions, each region having a relatively more magnetic segment and a relatively less magnetic segment, such that the plurality of regions are arranged so as to comprise alternating relatively more magnetic and relatively less magnetic segments, which regions are aligned at an angle other than in the plane of the surface of the regions to the direction of the resultant nonmagnetic forces such that the relatively more magnetic material has a tendency to travel at an angle to the direction of flow of the relatively less magnetic material thereby effecting the separation. Preferably each of the regions is aligned from to about with respect to each adjacent region.
