Types of Iron Ore: Hematite vs. Magnetite_SMM

2013-9-7  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 from rock during concentration. Magnetite ore is currently mined in Minnesota and Michigan in the United States as well as in taconite deposits in Eastern Canada.
