At Apex International, we specialize in the export and supply of premium-grade Dolomite Powder, delivering high purity, controlled chemical composition, and reliable performance for a wide range of industrial applications worldwide.
Our dolomite is sourced from carefully selected mineral deposits and processed in modern manufacturing facilities under strict quality control systems. This ensures optimal CaO and MgO content, low silica and iron impurities, fine particle size distribution, and consistent product quality for international buyers.
Dolomite Powder (Calcium Magnesium Carbonate – CaMg(CO₃)₂) is a highly versatile industrial mineral known for its excellent chemical stability, high whiteness, and strength-enhancing properties. Using advanced crushing, grinding, micronizing, and magnetic separation processes, we maintain precise particle size distribution and minimal impurities, meeting the specific requirements of various industrial formulations.
