Magnetite

As its name implies, it is magnetic; it and other inherently magnetic iron-containing minerals are described as being ferrimagnetic. Magnetite is in the hexoctahedral crystal class; in the 3-D crystal structure, the purple atoms are iron, and the red atoms are oxygen. Magnetite's greatest use is as an important iron ore for steel manufacture.

Iron: Source, Physical & Chemical Properties & Uses

Ans. Industrial iron making starts with iron ores, principally hematite, which has a nominal formula Fe 2 O 3, and magnetite, with the formula Fe 3 O 4.These ores are reduced to the metal by treatment with carbon which is called a carbothermic reaction. The adaptation is typically conducted in a blast furnace at temperatures of about 2000°C.
