Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

Applications
Steelmaking Industry:
Converter Inner Refractory: Dolomite is used as a refractory material in
steelmaking converters due to its high melting point and resistance to thermal
shock.
Slagging Agent: It helps in the removal of impurities (such as silica and alumina) during steel production by forming slag.
Cement Industry:
Raw Material: Dolomite is used as a source of magnesium oxide (MgO) in cement production, improving the strength and durability of the final product.
Glass Manufacturing:
Flux: Dolomite acts as a flux in glass production, reducing the melting temperature of silica and improving the workability and chemical resistance of glass.
Ceramics:
Raw Material: It is used in ceramic production to enhance strength, thermal stability, and whiteness of ceramic products.
Agriculture:
Soil Conditioner: Dolomite is used to neutralize acidic soils and provide essential nutrients like calcium and magnesium.
Fertilizer: It is a source of magnesium, which is vital for plant growth.
Construction and Decoration:
Building Stone: Dolomite is used as a decorative stone in construction due to its aesthetic appeal and durability.
Paint Filler: It is used as a filler in paints to improve texture and durability.
Chemical Industry:
Raw Material: Dolomite is used in the production of magnesium-based chemicals and as a source of magnesium oxide.
Environmental Protection:
Water Treatment: Dolomite is used to neutralize acidic water and remove heavy metals from wastewater.
Dolomite package: in 50kg or 1250,1300,1350KG bags
