ABSTRACT:
Electrically-conducting particles may be separated from mixtures thereof containing non-conducting particles by conveying the mixture through a magnetic field oriented angularly with respect to the part of conveyance. The magnetic field induces magnetic poles in the conducting particles, causing them to deflect from the path of movement of the mixture as they attempt to move in the angular orientation of the magnetic field. The non-conducting particles are unaffected, so that a separation may be achieved. The invention is applicable to a wide variety of materials, such as ores or tailings which contain desired electrically-conducting particles, such as, iron oxide, and unwanted gangue constituents.
