Specifications of Limestone CaCO₃ (Calcium Carbonate) = 95–98%

Explore a wide selection of Limestone.

lIMESTONE

Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO₃) in the form of the mineral calcite. With a high CaCO₃ content, this product is classified as high-grade limestone, making it highly suitable for heavy industrial applications such as cement manufacturing, steelmaking flux, production of quicklime, and as a filler in the chemical, paper, and paint industries.

The high purity level ensures excellent chemical stability, good reactivity, and consistent end-product quality.

Chemical Composition (Typical Laboratory Result)

CaCO₃ (Calcium Carbonate) = 95–98%

CaO (Calcium Oxide) = 53–55%

MgO (Magnesium Oxide) = ≤ 1.0%

SiO₂ (Silicon Dioxide) = ≤ 1.5%

Fe₂O₃ (Iron Oxide) = ≤ 0.2%

Al₂O₃ (Aluminum Oxide) = ≤ 0.5%

Loss on Ignition (LOI) = 42–44%

Moisture Content = ≤ 1%
