Calcined dolomite is essential in steel production, used as a fluxing agent to remove impurities like sulfur, phosphorus, and silicon from iron ore. The high concentrations of calcium oxide (CaO) and magnesium oxide (MgO) in calcined dolomite fuse with these impurities, forming slag that is removed, resulting in cleaner, higher-quality steel. With over 50% CaO and 30% MgO content, our calcined dolomite also protects furnace linings by preventing slag from dissolving the refractory materials.

In glass manufacturing, calcined dolomite serves as a critical stabilizer, enhancing both the chemical durability and strength of the final product. It is mixed with silica sand and soda ash before being heated to high temperatures, improving the glass’s resistance to environmental factors, opacity, and surface finish. Our calcined dolomite, with high levels of CaO and low impurities, is particularly well-suited for producing high-quality soda-lime glass used in products like windows, bottles, and containers.

Calcined dolomite is widely used in agriculture to correct soil pH, especially in acidic soils. When applied, it raises the pH, making the soil more alkaline, which improves nutrient absorption and promotes healthier plant growth. The high levels of calcium and magnesium in calcined dolomite also provide essential nutrients, making it an ideal soil amendment for boosting crop yields and improving soil quality.
