Quick Lime Lumps

Quicklime is a Calcium oxide formed by calcining calcium carbonate (limestone) so that carbon dioxide is liberated. Quicklime is also called as burnt lime, handpicked lime, calcining lime, lump lime or caustic lime. A caustic substance that is prepared by burning calcium carbonate limestone at approximately 900 degrees Celsius, at these high temperatures carbon dioxide is driven off and the limestone is converted to Quicklime.

A chemical compound with formula (CaO) it is a whitish, odourless alkaline substance, which does not dissolve well in water. It can be used as a lining material. Major use is in various industrial processes like metal smelting, paper bleaching, sulphur neutralization in sugar and so many. It is used in many waters and wastewater treatment operations such as softening. Quicklime is created by heating limestone as shown in the following equation:

Chemical formula: CaCO3 + HEAT = CaO + CO2
