It is vital in the production of countless materials. Lime, or calcium oxide (CaO), is derived from high quality natural deposits of limestone, or calcium carbonate (CaCO3). Limestone is a sedimentary rock that formed millions of years ago as the result of the accumulation of shell, coral, algal, and other ocean debris.
