Iron Oxide
Mill Scale is a layered and brittle material generated in the surface of billets, rebar, wire rod, merchant bar and profiles when they are manufactured during a rolling process. Mainly composed by iron oxides (>98%) FeO (Wustite), Fe2O3 (hematite), Fe3O4 (magnetite).
The mill scale is a perfect substitution for primary iron ore, with even better quality due to a higher iron content. The main industrial applications are integrated steel making, cement clinker, Ferroalloys, colored glass, oxide pigments, flocculant production, counterweights, and magnets.
