What is Dolomite Powder?
Dolomite powder is a common rock-forming mineral with a composition of calcium magnesium carbonate. Its chemical formula is denoted as CaMg(CO3)2.
Its whiteness and purity are two important factors that make it a raw material for the paint industry. Further, its hardness and density make dolomite powder a vital ingredient in the construction industry.
Dolomite is the second most abundant carbonate mineral. It exists as the primary component of sedimentary and metamorphic rock. It is also commonly found in hydrothermal deposits.
Dolomite is the primary ore for magnesium metal and is quarried for building material, road stone, or refractory brick production.

Properties of Dolomite Powder
- Dolomite powder has a rough and abrasive texture.
- It may appear pinkish, white, yellow, grey, colorless or even black/brown.
- According to the dolomite manufacturer its luster may vary from vitreous to pearly to dull.
- Also, this raw material for the paint industry and glass industry is opaque.
- Its value on the hardness scale lies between 3.5 to 4 Mohs.
- Further, it has both adsorption and absorption tendency towards moisture.
- Dolomite powder disperses in the water but remains insoluble.
- Its oil absorption capacity is low.
- It is non-explosive and non-inflammable on combustion.
- Lastly, it is a poor conductor of electricity.
Uses and Applications of Dolomite Powder
Soap Industries
Every dolomite manufacturer supplies dolomite powder to the soap and detergent industry. It is an ideal base filler for detergents and soaps to change their consistency. Further helps the soaps to disperse evenly and enhances their solubility.
Glass Industries
The calcium oxide and magnesium oxide present in dolomite improve the reaction time during the glass manufacturing process. The glass-making process requires a pure white mineral to produce clear transparent glass. So, white dolomite with minimum iron content, i.e., 0.05% is used. However, in colored glass making, 0.25% of iron containing dolomite powder is used.
Paint Industries
Our dolomite powder also serves as one of the primary raw materials for the paint industry. It is used as a filler in paint and serves as a white extender providing it with scrub resistance.
Agriculture
The magnesium content of dolomite powder makes it an excellent fertilizer for agricultural fields. Further, it is also used as a soil neutralizer to control soil acidity.
Building Material and Putty
Due to its ability to adsorb water, high-density ratio, and high surface hardness, it is used in building materials like cement or putty.
Rubber Industries
Dolomite from Aravali Minerals is also supplied to the rubber industry, which helps maintain the hardness and softness of rubber. Besides, it also increases the volume of rubber.
