What Are the Uses of Magnetite? (with picture)

22/02/2021  Several minerals serve as sources of iron ore, and magnetite is one of the most important. Large quantities of magnetite are mined and processed into iron for use in the production of steel. Most of the magnetite mined annually is used for this purpose. Much smaller amounts of magnetite are used in other but no less important ways.

Magnetite - Oresome Resources

Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a highly magnetic substance used primarily in steel manufacturing and coal washing. There are more than 20 identified magnetic deposits and prospects located across South Australia, Western Australia, Queensland and Tasmania. Magnetite occurs in nearly all igneous and metamorphic rocks and usually only in small particles or ...

“Mining Magnetite for your future.”

Magnetite is a valuable source of iron ore and is mainly used in making steel. Magnetite is a ferrimagnetic mineral with definite north and south poles and a chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth, and these magnetic properties led to lodestone being used as an early ...

However, the most significant use of magnetite lies in its status as an ore of iron and its industrial importance in manufacturing steel. Magnetite is an important material component of power plants as it is used to generate electricity. Magnetite, owing to its magnetic properties, is widely used in compasses and other navigation devices.
