Dolomite Powder
Calcium Magnesium Carbonate · CaMg(CO₃)₂
India's trusted dolomite — 94% brightness, 96% whiteness. A vital raw material for paints, glass, soaps, agriculture, rubber and the iron & steel industry.
Overview
Satellite Chem India is a leading dolomite manufacturer and exporter in India. Dolomite is a common rock-forming mineral with a composition of calcium magnesium carbonate — CaMg(CO₃)₂ — used extensively in products like soaps, detergents, paints and animal feed.
Its whiteness and purity make it a prized raw material for the paint industry, while its hardness and density make dolomite powder a vital ingredient in construction. It also acts as an active ingredient in the iron and steel industry.
Dolomite is the second most abundantly found carbonate mineral, existing as the primary component of sedimentary and metamorphic rock. Satellite Chem India is the pioneer dolomite manufacturer that has maintained industry standards for generations.

- Non-explosive, non-inflammable
Applications
Where this mineral goes to work.
Soaps & Detergents
Ideal base filler that helps soaps disperse evenly and enhances solubility.
Glass
CaO and MgO improve reaction time; low-iron white dolomite (0.05% Fe) for clear glass.
Paints
White extender filler providing scrub resistance.
Agriculture
Magnesium-rich fertilizer and soil neutralizer to control acidity.
Rubber
Maintains hardness/softness balance and increases rubber volume.
Building & Putty
High density ratio and surface hardness for cement and putty.
Iron & Steel
Active ingredient in iron and steel manufacturing.

Specification Table
Dolomite at a glance, industry by industry.
| Industry Application | Key Composition (min %) | Max Impurities (%) | Physical Properties | Primary Functional Role |
|---|---|---|---|---|
| Steel & Metallurgy (Flux) | MgO ≥ 19.0 – 21.0% | SiO₂ ≤ 1.5%, Al₂O₃ ≤ 1.0%, S/P ≤ 0.05% | 10 – 40 mm lumps (blast furnace) | Slag conditioner; adjusts slag basicity, removes impurities and protects refractory lining. |
| Refractories | MgO ≥ 20.0 – 22.0% | SiO₂ ≤ 1.0%, Fe₂O₃ ≤ 1.0% | Dead-burned / sintered lumps or bricks | Raw material for basic refractory bricks; protects EAF/BOF linings from high temperatures. |
| Glass Production | MgO ≥ 20.0% | Fe₂O₃ ≤ 0.05 – 0.10%, SiO₂ ≤ 0.5% | 16 – 60 Mesh (granular) | Supplies both MgO and CaO; lowers melting temperatures and prevents devitrification. |
| Ceramic Glazes & Bodies | MgO ≥ 19.5% | Fe₂O₃ ≤ 0.15%, SiO₂ ≤ 1.0% | 200 – 300 Mesh | Modifies thermal expansion; improves thermal shock resistance and glaze matte finish. |
| Agriculture & Fertiliser | MgO ≥ 15.0 – 20.0% | Neutralising value (CCE) ≥ 95% | 60 – 100 Mesh (powder or granulated) | Soil conditioner; neutralises soil acidity while supplying essential Mg and Ca nutrients. |
| Paints & Putty Filler | MgO ≥ 19.0% | SiO₂ ≤ 2.0% | Whiteness 90 – 95% | Cost-effective functional filler; enhances scrub resistance and chemical stability. |
