magnetite is used almost entirely by the New South Wales coal mining industry during coal beneficiation. When finely milled, magnetite remains suspended in water, producing a dense medium suitable for separating impurities from coal. The magnetite is easily recovered by applying a magnetic field.

of iron ore using a magnet. In 1854 Palmer proposed a magnetic separator with magnet polarities alternating along the direction of the material movement. Up until the end of the 19th century, methods of magnetic beneficiation were developed rather slowly, as a result of the absence of successful magnetic separator designs.
