nace, where iron ore is reduced to metallic iron. Currently, the group of iron formation-hosted ore deposits including the famous banded iron formations (BIFs) account for the majority of world production (Clout and Manuel, 2015). After a rst mechanical processing of the ores, two particle fractions can be distinguished: lump (31.5 to 6.3 mm) and
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite.As the mineral known as hematite, Fe 2 O 3 is the main source of iron for the steel industry.
The content and stability of FeO in sinter are the important comprehensive indicators to assessing the sintering production. They not only reflect the quality and energy consumption of agglomerates, but also influence the smelting results of blast furnace. The effects of the FeO content of original ores on the FeO content in sinter and the creating ability of calcium ferrite are discussed in ...

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 …
Iron Content. The most easily seen ore of iron that is found is hematite. Now to find in which ore of iron, the iron content is maximum we can use mass percentage.
Even elemental iron (such as in tyre wire) will oxidise to Fe2O3 under normal kiln conditions, if it remains reasonable finely divided. The FeO content in iron ore should not be a problem. Indeed some plants have used magnetite (FeO.Fe2O3) as their iron corrective, without the slightest detrimental effect. Regards, Ted. Reply
Dec 08, 2020· Iron likes to be in the +2 and +3 states, which is what you find in FeO (+2) and in Fe2O3 (+3). In the compound magnetite (which is written Fe3O4 but it is really FeO: Fe2O3), iron exists in both states. But under certain conditions you can create +4, +5 or the very rare +6 iron compounds.
