LIME BURNING PROCESS . Introduction . The practice of burning limestone to produce quicklime is, almost literally, as old as the hills. In terms of basic chemistry and materials, the process involves the conversion of calcium carbonate, CaCO 3, to the more useful calcium oxide, CaO. Calcium oxide is a very reactive substance.
