  • HOW TO CALCULATE EFFICIENCY OF YOUR LIME BURNING

    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.

    The major synthetic pathway is circular: limestone is mined, then it is heated which produces lime and carbon dioxide. The lime is then mixed with water and C O X 2 is added (bubbled in/through) and C a C O X 3 precipitates. It is then dried. Purification depends on the source; how impure it is to start with.

    Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.
