Mill Scale

Product Details

Mill scale — a ferrous by-product formed on the surface of steel during hot rolling operations at steel mills. Rich in iron oxide (typically 60–70% Fe content), mill scale is a valuable raw material in cement manufacturing, sinter plants, and iron recovery processes. During hot rolling, the outer layer of steel oxidizes, creating a thin, brittle scale that flakes off during cooling and handling. This scale is collected, processed, and supplied to industrial buyers requiring consistent iron-rich feedstock. Mill scale is used as a fluxing agent in cement production, as a raw material in sinter plants for iron ore agglomeration, and in chemical processes for iron oxide recovery. Available in bulk lots with iron content analysis documentation. Sourced from steel rolling mills in India and Europe with quality verification before dispatch.
