Uses of Limestone - ScienceStruck

Limestone rock is a sedimentary rock which forms in the process of sedimentation at the bottom of lakes and oceans, or in caves. It is mainly composed of mineral calcite and aragonite, both of which are crystal forms of calcium carbonate. A limestone with 95 percent or more of calcium carbonate by weight is known as a high-calcium limestone.

Lime kiln - Wikipedia

A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction takes place at 900 °C (1650 °F; at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which ...
