Mill scale (often known simply as 'scale') refers to the thin, flaky texture that forms on the outer surface of hot-rolled iron oxides and metals. It is a by-product of manufacturing hot-rolled metal plates and sheets, occurring as the surface oxidizes during the heating, conditioning and hot rolling processes.

Mill scale is the metallurgical waste produced by the rolling mill in the steel hot rolling process. It contains a substantial percent of iron, including traces of other elements.

Mill scale is a very at- tractive industrial waste due to its richness in iron [about = 72 % Fe) [2]. In the whole world, 13.5 million tons of mill scales are generated annually [3]. Mill scale is suitable for direct recycling to the blast furnace via sintering plant [4]. Ap- proximately, 90% of mill scale is directly recycled within

In this project, iron mill scale has been used to produce iron powder that can be used within the Powder Metallurgy process. To achieve this objective, the iron mill scale needs to be refined. This involve the work of grinding the iron mill scale to an effective particle size, which is 300μm. Latter, the grounded iron mill scale will undergo the magnetic separation process.

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
