Effect of Grinding Time of Mill Scale on the

Mill scale is a steelmaking by-product 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 (α-Fe 2O 3) and Magnetite (Fe 3O 4). The chemical composition of mill scale varies according to the type of steel produced and the process used.
