For the purpose of this discussion the iron ore oxide hematite ((Fe 2O 3)) will be shown. On a side note Hematite gets its name from the Greek word meaning blood like because of the color of one form of its powder. The Ancient Greeks believed that large deposits of hematite were formed from battles that were fought and the blood from these

Iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron (Fe). It almost always consists of iron oxides the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world s iron and steel industries.
