Types of Iron Ore: Hematite vs. Magnetite_SMM Shanghai Metals Market
In addition, hematite ore only goes through one stage of screening and crushing, while magnetite has an additional round of processing. 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.
