Sintering: A Step Between Mining Iron Ore and Steelmaking

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.
