High-calcium quicklime is lime made from rich deposits of high-calcium limestone containing less than 2% magnesium carbonate. Calcium oxide (CaO), commonly known as lime or quicklime, is a widely used chemical compound. It is a white, alkaline, and crystalline solid.

Quicklime is produced by heating limestone as shown in the following equation:

Quicklime is created by heating limestone as shown in the following equation:

CaCO₃ + HEAT = CaO + CO₂

High-calcium quicklime provides superior chemical performance. It will deliver exceptional performance for acid-neutralization, SO₂-absorption, sludge-stabilization or other industrial-alkali applications
