Ferromagnetic Minerals: These are the most strongly magnetic minerals and are the ones most commonly associated with "magnetism."
* Magnetite (Fe3O4): The most common magnetic mineral, and the one that gives the phenomenon its name. It's a black oxide of iron and is naturally found in many rocks.
* Pyrrhotite (Fe1-xS): Another sulfide of iron, but with varying amounts of iron. It can be strongly magnetic, especially in its hexagonal form.
* Hematite (Fe2O3): While not always magnetic, hematite can be weakly magnetic in certain forms, especially in its "specular" form.
Other Magnetic Minerals: While not as strongly magnetic as the ferromagnetic minerals, these still exhibit magnetic properties.
* Ilmenite (FeTiO3): A titanium-iron oxide that can be weakly magnetic.
* Lodestone: This is a type of magnetite that exhibits strong natural magnetism, often due to the presence of other minerals like hematite.
* Goethite (FeO(OH): A hydrated iron oxide that can be weakly magnetic.
Note:
* Magnetic Properties: The strength and type of magnetism in these minerals depend on factors like their composition, crystal structure, and even the presence of other minerals.
* Applications: These magnetic minerals have been used for centuries, from compasses to medical treatments to modern technology.
