At Mississippi Lime,our calcium oxide (CaO),or commonly referred to as quicklime,is a high calcium content derivative of our 98.5% pure calcium carbonate (limestone).Calcium oxide is produced by heating calcium carbonate to 2000 degrees F where carbon dioxide disassociates as a gas from the calcium carbonate:Products - Linwood Mining Minerals CorporationCalcium Oxide is produced from high calcium limestone that is calcinated through a rotary kiln.Finished product is white in color and screened to customer specification.Possibility of Calcium Oxide from Natural Limestone Although various heat storage materials can be used in CHP,for the high temperature range we use calcium oxide (CaO) made from natural limestone (CaCO 3),which is widely distributed in Japan .This is because CaO from limestone is low cost,safe to use and it has a high storage density (1.86 MJ/kg).
