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 3 MgCO 3 + heat 2CO 2 + CaO MgO To complete the
