In America about 15-20 million tons of iron ores were separated with ferrosilicon in 1952. A powder with about 15% Si=content is used because in it the magnetic properties are well distinguished and the specific gravity is high. With a Si=content of 18-20% the spec, gr. is lower and the limit of magnetizability is near.

Working principle. The magnetic separator is used to recycle the powdered granules to remove iron powder, etc. The magnetic separation is mainly carried out by the phenomenon of magnetic stirring when the drum rotates. Non-magnetic particles and magnetic particles are attracted to the surface of the drum by the magnetic force in the magnetic field.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
