Limestone (Calcium Carbonate)

Description

Limestone – High-Quality Calcium Carbonate (CaCO₃) for Industry

Limestone is a versatile mineral composed primarily of calcium carbonate (CaCO₃). It is one of the most widely used raw materials in construction, metallurgy, agriculture, chemicals, and environmental industries. With its abundance and diverse applications, limestone plays a critical role in steelmaking, cement production, water treatment, and soil conditioning.

At Call2Supply, we supply Iranian-origin limestone in various grades and forms, including raw limestone, crushed limestone, quicklime, and hydrated lime, tailored to international buyer requirements.

• Applications of Limestone

Steel Industry: Flux material for removing impurities in blast furnaces and converters

Cement & Construction: Main raw material in clinker production and aggregates

Agriculture: Soil neutralizer and animal feed additive

Chemicals: Base material for lime, calcium carbide, soda ash, and more

Environmental Uses: Water treatment, flue gas desulfurization, waste neutralization

 

• Packaging & Delivery

-Bulk shipments in vessels (handymax, supramax, panamax)

-Jumbo bags (1–1.5 MT) or 25–50 kg PP bags for powder products

-Flexible **FOB Iran ports, CFR, CIF** shipping options
