Mill scale metal, also known as iron oxide, is a byproduct of the steelmaking process. It forms on the surface of steel during hot-rolling or forging operations and is typically removed and discarded. However, mill scale metal has valuable properties and uses that make it a valuable resource for various industries. One of the primary uses of mill scale metal is in the production of cement. It is a key ingredient in the cement manufacturing process, as it provides iron oxide which acts as a coloring agent and enhances the strength and durability of the final product. The iron oxide content in mill scale metal also helps in adjusting the chemical composition of the cement to achieve the desired properties. In addition to cement production, mill scale metal is used in various other applications. It can be used as a raw material in the production of ferrous alloys, such as stainless steel and cast iron.

When mixed with other metals, it can improve their hardness, corrosion resistance, and other mechanical properties. Mill scale metal is also used in the manufacturing of iron powder, which is widely used in industries such as metallurgy, electronics, and automotive. Iron powder is used in the production of magnetic materials, such as magnets and magnetic recording media. It is also used in the production of abrasive materials, like grinding wheels and cutting tools. Furthermore, mill scale metal is utilized in the production of fertilizers, specifically as a source of iron. Iron is an essential nutrient for plants, and mill scale metal provides a cost-effective source of iron for agricultural applications.
