Mill scale is a steelmaking byproduct from the rolling mill in the steel hot rolling process. Mill scale contains both iron in elemental form and three types of iron oxides: wustite (FeO), hematite (αFe 2 O 3) and magnetite (Fe 3 O 4). The chemical composition of mill scale varies according to the type of steel produced and the process used.

Mill scales are oxidized iron from the continuous casting line (CC), hot strip mill, or bar and wire rod mills; these oxidized iron materials are composed mainly of FeO and with TFe of >70 %. Mill scales are able to provide heat in the iron ore sintering process owing to the oxidation of FeO to Fe 2 O 3, and save some fuel.

What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its highgrade concentrate of iron and its abundance. . Iron ore containing over 60% hematite or ...
