Calcium Carbonate (5-15) CM

Limestone (Calcium Carbonate - CaCO3) in the 5-15 cm size range is a natural, high-purity stone product obtained from the renowned Al Minya quarries in Upper Egypt, a region globally recognized for its superior quality calcium carbonate resources. This limestone is extracted, screened, and sized to meet industrial and construction requirements. Key Specifications: Chemical Composition: Calcium Carbonate (CaCO3): 96-99% Magnesium Carbonate (MgCO3): <1% Silica (SiO2): <0.5% Iron Oxides (Fe2O3): <0.1% Whiteness (Reflectance): 90-95% Hardness (Mohs scale): 3 Density: 2.6-2.7 g/cm3 Moisture Content: <0.2% Size Range: 5-15 cm (screened and graded) Applications & Usage: 1. Steel Industry (Flux Stone): Used as a flux in blast furnaces for removing impurities during steelmaking. 2. Cement & Construction Materials: Serves as a key raw material for clinker production and as aggregate in various construction applications. 3. Lime Production: Primary feedstock for producing quicklime (CaO) and hydrated lime (Ca(OH)2) through calcination. 4. Chemical Industry: Neutralization of acidic effluents and industrial waste. Feedstock for calcium-based chemical compounds. 5. Glass Manufacturing: Provides calcium oxide content to stabilize silica and reduce melting temperatures. 6. Fertilizers & Agriculture: Crushed limestone improves soil quality, balances pH, and provides essential calcium for crops. 7. Environmental Applications: Used in flue-gas desulfurization (FGD) to reduce sulfur dioxide emissions. Water treatment applications for pH adjustment and remineralization.
