For over 5,000 years, calcite has been used to manufacture lime (CaO, calcium oxide). Although the equipment used to do this has changed across the centuries, the basic process remains the same. Rocks rich in calcium carbonate are heated to high temperatures so the CaCO3 will burn to form CaO and CO2 gas.
