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, 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, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as iron ore.

An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process steps are described in more detail in the following sections.
