High Calcium Limestone
What Is High Calcium Limestone? High Calcium Limestone is a natural sedimentary rock composed of ≥95% calcium carbonate (CaCO₃). It is widely used across industries such as cement, metallurgy, flue gas desulfurization (FGD), and agriculture due to its high CaO yield, low impurity content, and excellent reactivity. Key Features ✔ High CaCO₃ (≥95%), CaO ≥ 52% ✔ Low MgO (<2%) ✔ High Whiteness (≥90%) – ideal for paints & paper ✔ Customizable particle sizes (1μm to 50mm) Comparison with Dolomitic Limestone: Property High Calcium Limestone Dolomitic Limestone Main Composition CaCO₃ (≥95%) CaMg(CO₃)₂ MgO Content <2% 10–20% Calcined Product CaO CaO + MgO Key Applications Cement, FGD, Chemicals Metallurgy, Agriculture Available in powder, granular, or lump form with customizable mesh sizes (100, 200, 325 mesh) and packaging (25kg bags, 500kg–1t jumbo bags, bulk tanker). Production Process & Quality Control 1.
