High-calcium Quicklime. High-calcium quicklime is lime made from rich deposits of high-calcium limestone containing less than 5 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.
FACTORS AFFECTING QUALITY OF CaO As stated previously the calcium carbonate is heated in the rotary or vertical kilns to drive away CO 2 from limestone CaCO 3 to pr oduce calcium oxide CaO. This process is called calcination. Calcination conditions highly affect the quality of quicklime CaO that results from this process.
