In metallurgy, dolomite serves several important functions due to its unique chemical and physical properties. One primary use of dolomite in metallurgy is as a fluxing agent in steelmaking and iron smelting processes. Dolomite functions as a flux by lowering the melting point of silica, alumina, and other impurities present in iron ore, allowing them to be more easily removed during the smelting process. This fluxing action helps to improve the efficiency of iron and steel production by facilitating the formation of slag, which acts as a protective layer on the surface of molten metal, preventing oxidation and reducing heat loss.

Moreover, dolomite serves as a source of magnesium oxide (MgO) in metallurgical applications. Magnesium oxide is a valuable refractory material used in the production of refractory bricks, linings, and crucibles for high-temperature furnaces and reactors. Dolomite-derived magnesium oxide exhibits excellent thermal stability, chemical resistance, and mechanical strength, making it suitable for use in harsh metallurgical environments.

Additionally, dolomite is utilized as a fluxing agent in non-ferrous metallurgy processes, such as copper, nickel, and aluminum production. In these processes, dolomite helps to remove impurities, improve slag fluidity, and enhance metal recovery rates.
