Dolomite for steel manufacturing, glass production, and construction. CaMg(CO₃)₂ with controlled chemical composition.
Our dolomite [CaMg(CO₃)₂] is quarried from extensive deposits in Nigeria's Abuja, Kwara, and Ogun states. These deposits produce high-quality dolomite with consistent MgO content, suitable for refractory, agricultural, and glass manufacturing applications.
Dolomite serves as a critical flux material in steelmaking, a magnesium source for agriculture, and an essential component in glass production. Our quarrying and processing operations deliver material meeting international specifications for various industrial end-uses.
Certified quality parameters verified by independent laboratories.
