Introduction to Calcined Dolomite

Dolomite powder is an anhydrous carbonate mineral powder primarily composed of calcium and magnesium carbonate (CaMg(CO₃)₂). When processed through calcination, dolomite transforms into burnt dolomite or dead-burned dolomite, creating a highly valuable industrial material. The resulting calcined dolomite powder price per ton export high purity burnt white dolomite has become a critical factor in global trade for industries requiring premium mineral additives.

The thermal decomposition during calcination (typically at 800-900°C) converts calcium carbonate and magnesium carbonate to their respective oxides. This process enhances physical and chemical properties, making it suitable for demanding applications in steel, ceramics, glass manufacturing, and environmental applications. According to recent studies in Advanced Materials Research (2023), the surface area of calcined dolomite increases from 2-6 m²/g to 35-120 m²/g after activation, significantly enhancing its reactivity.

Industry Applications

Calcined dolomite powder price per ton export high purity burnt white dolomite is utilized across multiple high-value industries due to its unique properties:

Steel Manufacturing

In iron and steel production, burnt dolomite serves as a refractory lining material and slag conditioner. Its high melting point (2400°C) and excellent resistance to thermal shock make it indispensable in furnaces. According to the International Iron and Steel Institute, global steel production consumes over 18 million tons annually, with premium grades commanding 15-20% price premiums.

Environmental Applications

As a cost-effective desulfurization agent in flue gas treatment systems, calcined dolomite effectively removes SO₂ from exhaust streams. Research published in the Journal of Cleaner Production confirms that dolomite-based sorbents achieve up to 98% sulfur capture efficiency at optimal temperatures. The European Environmental Agency estimates the market will grow 8.5% annually through 2027.

Professional FAQ Section

Q: What determines the price variation in calcined dolomite powder per ton?

A: The primary cost factors are purity grade (MgO content), whiteness index, mesh size, packaging specifications, and order volume. Production costs are influenced by calcination energy consumption rates, with premium grades requiring 25-30% more energy input than standard grades.

Q: What are the standard international specifications for refractory-grade dolomite?

A: According to ASTM C544, refractory grades must maintain MgO content >36%, SiO₂ 2O₃ 3 with thermal stability at 1700°C. Our export-grade calcined dolomite meets and exceeds these specifications.

Q: How does mesh size impact application performance?

A: Particle size distribution directly affects dissolution rates and reactivity. Glass manufacturing requires 200-325 mesh for uniform melting, while plastics reinforcement needs 2500-5000 mesh particle sizes. Our precision milling technology ensures ±2% distribution tolerance.

Q: What packaging options are available for export orders?

A: We offer multiple options: 1) 25kg PP woven bags with PE liner (standard), 2) 1-ton jumbo bags with moisture barrier, 3) 50kg moisture-proof kraft paper bags, and 4) customized packaging solutions meeting IMDG Code requirements for hazardous material transport.

Q: How should calcined dolomite powder be stored?

A: Store in cool (15-25°C), dry (

Industry Trends & Market Forecast

Recent analysis indicates several critical developments affecting the calcined dolomite powder price per ton export high purity burnt white dolomite market:
