Magnesite (MgCO₃) – High-Quality Iranian Magnesium Carbonate

Magnesite (MgCO₃), also known as magnesium carbonate, is a naturally occurring mineral prized for its purity, stability, and wide industrial utility. This mineral serves as an essential raw material in steelmaking, refractory manufacturing, chemical processing, agriculture, and environmental management. With its high magnesium content and resistance to extreme heat, it plays a crucial role in producing magnesia (MgO), refractory bricks, fertilizers, and magnesium-based chemicals.

At Call2Supply, we provide premium Iranian magnesium carbonate in multiple grades and forms — including raw lumps, fine powder, caustic calcined magnesia (CCM), and dead burned magnesia (DBM). Each type is processed to meet international standards for chemical composition, particle size, and purity, ensuring consistency and optimal performance across industrial sectors.

Industrial Applications

Steel Industry:
Used in refractory linings for furnaces, converters, and ladles, magnesium carbonate materials provide excellent thermal resistance and durability. This enhances furnace lifespan, minimizes maintenance downtime, and boosts production efficiency.

Chemical Industry:
A key feedstock for magnesia (MgO), flame retardants, fertilizers, and other magnesium compounds, this mineral’s high purity ensures efficient chemical reactions and consistent product quality in industrial formulations.

Construction and Building Materials:
Increasingly used in magnesia boards, flooring, and insulation panels, it provides superior fire resistance, structural integrity, and thermal insulation. These properties make it a sustainable alternative to traditional building materials.

Agriculture:
As a natural source of magnesium, it enriches soil fertility and enhances plant and livestock nutrition. It improves crop yield and supports balanced mineral intake in animal feed formulations.

Environmental Uses:
Magnesium carbonate is effective in treating acidic wastewater and neutralizing industrial emissions. Its chemical stability aids in flue gas treatment, helping industries meet environmental standards responsibly.
