  • Strong field magnetic separators are used to separate fractions of substances with different magnetizability, which can be characterized by specifying the magnetic susceptibility, in mixtures of solid particles, which are usually in the form of small grains. Of particular importance is this method in the enrichment, treatment and recovery of iron ores and other minerals. Compositions in granular form are suspended in a mostly liquid carrier medium (turbidity) and exposed to the effect of a strong magnetic field transversely to their direction of flow or to the gravitational field. Non-magnetizable and only extremely weak magnetic particles remain unaffected by the magnetic field and are thus separated from the magnetizable and deflected by the magnetic field and retained particles.
