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.

The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an open-grained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
