Hematite | Fe2O3 - PubChem
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.
Iron Ore Pelletizing Process: An Overview
direct reduced iron (DRI). Generically, the iron ore products for ironmaking can be classified as shown in Table 1 . Pellets are balls formed by rolling moist concentrates and fines iron ores of different mineral-ogical and chemical composition, with the addition of additives and binder, in a horizontal drum or in an inclined disc [1, 4].
