What is lime? Lime is calcium oxide obtained by the calcination of limestone, kankar, and other calcareous substances at over 900°C. It was one of the most common construction materials before the advent of Portland cement. Wherever locally available, it is still a very popular and cheap construction material. It is used for plastering the interior surface of …

The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising mainly from the …

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 application of the lime sinter process is restricted by the high consumption of calcium, the large amount of slag and the poor alumina leaching property of clinkers. An improved lime sinter process based on the dry-sintering is proposed by adding Na 2 O-containing compounds to decrease CaO addition and increase alumina leaching property.
