Probably the most common ore of iron is hematite, which is predominantly Fe2O3. Other iron minerals are magnetite, which predominantly has the chemical formula Fe3O4 (sometimes written as FeO.Fe2O3), and pyrite, which predominantly has the chemical formula FeS2.

Hematite is a common iron-containing mineral that is a major source of iron ore. It is commonly mined for its iron content, which is used in the production of steel.
Magnetism is a mineral property that involves iron. Iron-containing minerals like magnetite and hematite are naturally magnetic and can attract other materials like iron filings.
Magnetite is an iron-containing mineral that exhibits natural magnetism. It is commonly found in certain types of rocks and possesses magnetic properties due to its iron composition. Magnetite is widely used in compasses and magnetic recording media.
Ferrite and Magnetite bot have magnetic properties.

When minerals containing iron are exposed to air and water, they can undergo a chemical reaction known as oxidation. This leads to the formation of iron oxide, commonly known as rust. Rusting can degrade the mineral, causing it to become weaker and eventually break down.
Peridot is composed of the mineral olivine, which is a silicate mineral containing magnesium and iron. Its characteristic green color is due to the presence of iron in its crystal structure.
A wurtzite is a dark brown mineral, a form of zinc sulphide, often containing iron and cadmium sulphides.
The formation of rust-like material on the surface of an iron-containing mineral when exposed to rain is primarily due to the oxidation process. When iron reacts with oxygen and moisture in the presence of water, it forms iron oxides, commonly known as rust. This chemical reaction is accelerated by the presence of electrolytes in rainwater, leading to the deterioration of the mineral's surface over time.
Pyrite is a non-silicate mineral. It is a sulfide mineral composed of iron and sulfur, not containing silicon and oxygen as found in silicate minerals.
