Magnetite is found in three kinds of deposits: . are to be looked for at the contacts of igneous rocks of the intermediate kind (diorite, etc.).
Magnetite is a rock mineral and one of the main iron ores. With the chemical formula Fe3O4, it is one of the oxides of iron. Magnetite 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. . Magnetite nanoparticles are also thought to form in soils, where they.

This oxygen combined with dissolved iron to form hematite and magnetite. . Press metal mining strategies change by the kind of mineral being mined.
Magnetite is an important source of iron ore and occurs in many igneous rocks. Milky quartz is a common mineral that is found in many different types of rocks.
Magnetite is a type of mineral that belongs to the spinel group of which several other minerals like graphite, chromite and hercynite are also members.
