Does quick lime occur naturally in nature?

Answer 1

Lime naturally occurs in the earth's crust, mostly containing carbonates and oxides. Quicklime is usually processed, and is rather caustic in nature.

Answer 2

Quicklime, also known as calcium oxide, is not found in nature in its pure form. It is produced by heating limestone (calcium carbonate) to high temperatures in a process called calcination. This process drives off carbon dioxide, leaving behind calcium oxide.
