Introduction 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 2 O 3) and magnetite (Fe 3 O 4). TheCan China trade tensions boil over to Australian iron ore?11/12/2020· Despite trade tensions and talk of more supply from Brazil, Chinese demand for Australia's iron ore remains strong. Credit: Getty In, Australia accounted for 53 per cent of global iron ore ...Recycling of steel plant mill scale via iron ore pelletisation .Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O 3 . To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.
