Product overview
Balanced calcium and magnesium chemistry
Dolomite is calcium magnesium carbonate, CaMg(CO₃)₂. Its dual calcium and magnesium chemistry makes it useful where limestone alone falls short, especially where magnesium is needed.
Our dolomite stands out for purity and consistency. Strict controls keep chemistry stable from the first ton to the last, protecting steel, cement, glass, agricultural and refractory processes from mixed or intermediary supply.
You receive material matched to your specification, verified on paper and proven in demanding industrial use.

Industrial applications
Six major uses for natural dolomite
Steel and metallurgy
Dolomite acts as a flux, removes impurities, forms slag and protects furnace linings through its magnesium content.
- Cleaner and more efficient melts
- Reliable slag chemistry
- Furnace-lining protection
Cement production
Dolomite serves as a raw material and additive in cement and construction products, supporting stable processing and predictable output.
- Stable carbonate chemistry
- Consistent large production runs
- Custom sizing for plant handling
Glass manufacturing
Dolomite supplies calcium and magnesium, improving durability and chemical resistance in finished glass.
- Low iron and controlled silica
- Strong, durable glass
- Low-iron grades available
Agriculture
Dolomitic lime corrects soil acidity while supplying calcium and magnesium for healthier growth on magnesium-deficient soils.
- Soil pH correction
- Calcium and magnesium nutrition
- Fine agricultural grades
Construction and infrastructure
Graded dolomite supports road bases, concrete, building products and general infrastructure work.
- Road-base aggregates
- Building-product raw material
- Durable graded sizes
Refractory materials
High magnesium content and thermal stability make dolomite important for refractory bricks and furnace linings.
- High-temperature resistance
- Chemical stability
- Refractory-grade chemistry
