Iron ore - Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...

Not All Iron Is Magnetic (Magnetic Elements)

Iron isn't the only element that displays magnetism.Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic.

Ferromagnetism - Wikipedia

Historically, the term ferromagnetism was used for any material that could exhibit spontaneous magnetization: a net magnetic moment in the absence of an external magnetic field. This general definition is still in common use. However, in a landmark paper in 1948, Louis Néel showed there are two levels of magnetic alignment that result in this behavior.
