Quicklime is obtained by 'burning' or heating calcium carbonate, which occurs in natural limestone deposits. This process is one of the oldest chemical operations discovered by man, being used all over the world. In India, for example, quicklime was used for waterproofing boats, while in ancient Greece, it was used as a ingredient of the ...

MANUFACTURING Lime proves to be a highly diverse ingredient for the manufacturing industry. It is fundamental to steel manufacturing. In a steelworks, lime is used to remove impurities to give steel the correct chemical composition. For each tonne of steel, up to 70 kg of lime is required. It is not possible to make steel without lime.

To produce quicklime in lime kilns, there are mainly three processes. The first stage is preheating. The second stage is calcining. And the third stage is cooling. In the preheating stage. The feed limestone is preheated by the exhaust hot air from the lime kiln, so that partially of the limestone will be calcined.

The following is a brief chemical formula of this process: (Limestone) CaCO3 + HEAT (Calcium Oxide) CaO + CO2. However, CaO is unstable in the presence of moisture and CO2. A more stable form of lime is calcium hydroxide Ca(OH)2. Therefore, 56 units of CaO plus 18 units of H2O results in 74 units of Ca(OH)2.
