Not All Iron Is Magnetic (Magnetic Elements)

Jul 03, 2019· 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.

Oct 21, 2020· The oldest known magnetic ore is ferrimagnetic iron ferrite. Iron ferrites, such as Fe3O4, exhibit similar behavior as ferromagnetic materials. As in ferromagnetic materials, there is an overall magnetization in the direction of the applied field although some of the spin of shorter magnitude are opposing the field decreasing the overall

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

Magnetite Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite
