  • HOW TO CALCULATE EFFICIENCY OF YOUR LIME BURNING PROCESS

    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. In fact, it is so ''lively'' that it is usually hydrated

  • BCCF Calcium Carbonate | Calcium Carbonate Processing and Production

    Most commercial producers use the recarbonisation method of PCC production where limestone is converted into calcium oxide (lime) and carbon dioxide by calcination at high temperatures. After calcination the lime is slaked with water and the resulting milk of lime is purified and re-carbonised with the carbon dioxide obtained directly from the calcination process.
