Lime (material) - Wikipedia

The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.

Lime Production: Industry Profile

Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). High-Calcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime CaCO
