    2019-6-11 · Sintering A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as 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). It s a major ingredient in steel.
