Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2).In the next step of the so-called clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2), aluminum oxide (Al 2 O …

Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.

Limestone Calcination Process. 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.

There are three main ways of slaking the Quicklime: in an excess of water to produce a putty; in a shortfall of water to produce a powder - hydrated or bag lime; in damp sand to produce a hot mix. Lime carbonation. Lime sets by absorbing water soluble Carbon Dioxide from the air. This process is called carbonation.
