Dolomite
Durable Mineral. Industrial Grade
Didwaniya Group supplies high-grade dolomite (CaMg(CO₃)₂) sourced from premium deposits and processed to industry specifications. Our dolomite is carefully crushed, screened, and quality-checked to meet the demands of metallurgical, agricultural, construction, and chemical industries worldwide
Dolomite (CaMg(CO₃)₂) is a naturally occurring carbonate mineral composed of calcium and magnesium. It commonly forms bedded deposits and crystalline masses and is widely used as a raw material in a variety of industrial applications. Dolomite’s balanced chemistry and physical properties make it suitable as a flux in steelmaking, a source of magnesium, and a stable mineral filler in manufacturing processes.
Didwaniya Group’s dolomite is mined and processed with strict quality controls to ensure uniform particle size, low impurities, and reliable performance. Our material undergoes inspection for physical properties and chemical composition so buyers receive a consistent product appropriate for demanding industrial uses.

Application
Dolomite is highly versatile: in metallurgical processes it acts as a flux and refractory aggregate in steel and ferroalloy production; in the chemical industry it is a feedstock for producing magnesia (MgO) and other magnesium compounds; in construction and ceramics it is used as a raw material and filler; in glass and enamel manufacturing it helps control viscosity and improve finish; in agriculture dolomite (agricultural lime) corrects soil acidity and supplies calcium and magnesium; and in plastics, paints, rubber and paper it serves as an inert filler and extender to improve mechanical and processing properties.
Storage Condition
Store in dry, clean, well-ventilated warehouses protected from direct rain and groundwater. Keep material on raised pallets or impermeable flooring to avoid contamination and moisture pick-up. Recommended relative humidity not more than 75% and storage temperature not exceeding 25°C for prolonged quality preservation.
