Limestone (CaCO₃) – High-Quality Calcium Carbonate from Iran

Limestone, composed primarily of calcium carbonate (CaCO₃), is among the most valuable industrial minerals worldwide. It serves as a key raw material in construction, metallurgy, chemicals, agriculture, and environmental sectors. Because of its chemical stability and purity, limestone plays a crucial role in cement manufacturing, steel refining, soil treatment, and water purification.

At Call2Supply, we supply Iranian-origin limestone in various grades and processed forms — including raw rock, crushed aggregates, limestone powder (GCC), quicklime, and hydrated lime. Each product is processed and quality-tested to meet international standards for performance and consistency.

Industrial Applications

Steel Industry:
Used as a fluxing material to remove silica and sulfur impurities during steelmaking, improving metal quality and furnace efficiency.

Cement & Construction:
An essential ingredient in clinker and cement production, as well as in concrete and road base aggregates.

Agriculture:
Applied as a soil neutralizer and nutrient source to enhance fertility and provide calcium for crops and livestock.

Chemical Industry:
A raw material for lime, calcium carbide, glass, soda ash, and many other chemical derivatives.

Environmental Protection:
Used in wastewater neutralization and flue gas desulfurization (FGD) systems to reduce industrial emissions.
