For Water Treatment, Environmental and Process Industries

Production

At moderate temperatures of approximately 800 °C, only the carbon dioxide from the magnesium carbonate is released. This results in a porous CaCO₃·MgO structure with a high internal surface area – providing the ideal basis for rapid reactions.

Typical Applications

• Drinking water conditioning and remineralisation in accordance with DIN EN 1017
• Mineral feed as a natural MgO carrier
• Air pollution control and exhaust air filtration, thanks to its open-pore structure
• Wastewater treatment (e.g. municipal wastewater treatment plants)

Your Benefits

• High reactivity while maintaining a consistent grading size
• Rapid release of valuable magnesium and calcium ions
• Low bulk density for easy handling and dosing

Production

By calcining at temperatures above 1,000 °C, the dolomite is completely converted into CaO·MgO. State-of-the-art kiln technology results in a T60 value of approximately two minutes and a pH value of > 12, making the material suitable for demanding process applications.

Typical Applications

• Raw material for the glass and ceramics industries
• Slag former in metallurgical processes
• pH regulation in chemical processes
• White pigment in high-quality formulations

Your Benefits

• Very high whiteness for visually sensitive products
• Extremely short dissolution times, enabling efficient process control
• Low residual CO₂ content for maximum chemical activity

• Standard grading sizes from 0/0.25 mm to 2/5 mm
• Available in bags, big bags or silo tanker deliveries
• Batch-specific certificates of analysis
• Application support provided by our laboratory team
