We are a prominent manufacturer, exporter and supplier of Dolomite Mineral Powder. Dolomite Mineral Powder or in common terms known as limestone powder is a composition of CaCO3 and MgCO3. The mineral is a double carbonate of calcium and magnesium with a granular structure. Properties includes natural whiteness, ease of dispersion, weather ability, reduces shrinkage, fissure development and water absorption. Dolomite mineral also contains impurities such as silica, alumina and iron oxide. We also make sure that the percentage of combined impurities does not go beyond 7% as per standard industrial usage during manufacture.
Variation of Dolomite Mineral Powder
The variation in Dolomite Mineral Powder is mainly observed in accordance to the lime and magnesia percentages found in the powder.
Calcitic dolomite: When the percentage of CaCO3 increases by 10% or more compared to the theoretical composition, the mineral is termed as calcitic dolomite, high-calcium dolomite or lime-dolomite.
Dolomitic limestone: When the percentage of MgCO3 decreases in comparison to the theoretical composition, the mineral is termed as dolomitic limestone.
Magnesian limestone: When the percentage of MgCO3 ranges between5 to 10%, the mineral is termed as magnesian limestone.
