Types of Iron Ore: Hematite vs. Magnetite

Types of iron ore: Magnetite. With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore. That means it has to be concentrated before it can be used to produce steel. However, the ore's magnetic properties help separate magnetite ore from rock during concentration.
