What is Quicklime and How is it Made?

After the limestone rocks are processed, they are transported to a lime kiln for calcination. This is the process where the limestone is heated to a temperature above 1,472ºF for decarbonation, i.e., removal of carbon dioxide in gaseous form, to produce quicklime. Almost half of the limestone's weight is lost as carbon dioxide.
