What is Dolomite Powder?
Dolomite powder is made by crushing and grinding dolomite, a mineral of calcium magnesium carbonate with the chemical formula CaMg(CO₃)₂.
Its whiteness and purity make it a valued raw material for the paint industry, and its hardness and density make it a vital ingredient in construction.
Dolomite is one of the most abundant carbonate minerals after calcite. It is the main mineral in dolostone, a sedimentary rock, and in dolomitic marble, and it is also found in hydrothermal deposits.
Dolomite is also an ore of magnesium metal and is quarried for building material, road stone and refractory brick production. For a full breakdown by industry, see our guide to Dolomite Powder Uses

Properties of Dolomite Powder
Here are the key physical and chemical properties of the dolomite powder supplied by Aravali Onyx.
- 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 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
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, which makes dolomite essential for rubber industry.
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, dolomite 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.
