Lime is made from indigenous limestone or chalk rock, one of the most abundant materials in the Earth's crust. Limestone and chalk are both sedimentary rocks and are chemically known as calcium carbonate. When crushed or ground, they are widely used as aggregates and building products. As a raw material, calcium carbonate can also be processed […]

How it's produced: Quicklime is produced by heating crushed limestone to around 1,100 degrees Celsius in a shaft furnace or rotary kiln. The heating of limestone releases carbon dioxide, leaving calcium oxide (CaCO 3 produces CaO + CO 2).After heating, the quicklime is crushed and then milled to the appropriate fraction.

Quicklime. When a calcium limestone or chalk rock, that comprises mainly of calcium carbonate (CaCO 3), is heated in a kiln, it changes by a process called calcination into quicklime also known as 'burnt lime' and chemically is mainly calcium oxide (CaO), and the calcination process releases a gas from the rock which is carbon dioxide (CO 2).. …
