DOLOMITE

Dolomite Powder is a finely ground natural mineral composed primarily of calcium magnesium carbonate (CaMg(CO₃)₂). It is widely used in agriculture, construction, metallurgy, water treatment, and various industrial applications due to its high neutralizing value and well-balanced calcium–magnesium content. Its consistent quality, fine particle size, and chemical stability enhance its effectiveness in improving soil conditions, strengthening construction materials, and supporting efficient industrial processes. These characteristics make dolomite powder a reliable and versatile solution for a wide range of commercial and industrial needs.

Chemical Specification (Laboratory Tested)

Parameter

MgO (Magnesium Oxide) = 23.25 %
CaO (Calcium Oxide) = 31.42 %
Neutralizing Value (as CaCO₃ Equivalent) = 136.47 %

A neutralizing value above 100% indicates superior acid-neutralizing capacity compared to pure CaCO₃ standard.

Form: Dry fine powder
Specific Gravity: ±2.8–2.9
Bulk Density: 0.85–1.1 ton/m³ (depending on mesh)
Moisture Content: < 2% (typical)
