Quicklime, often referred to as either calcium oxide (CaO) or lime, is manufactured by heating the raw ingredient 'limestone' or 'calcium carbonate' in large kilns. This process removes CO 2 that is trapped in the stone leaving behind CaO and other minor mineral constituents. This CaO molecule is what we consider to be high calcium ...

Heat your calcium carbonate directly on the flame until it becomes red hot. Do this for about 23 minutes. The rock will decompose on heating to create calcium oxide (quicklime) and carbon dioxide. After it is apparent that the rock has been cooked and decomposed, turn the heat off.

Limestone (Calcium Carbonate CaCO3) is burnt in a kiln giving off Carbon Dioxide (CO2) gas and forming Calcium Oxide (CaO) which is commonly known as Quicklime or Lumplime. It needs to be burnt at 900°C to ensure a good material is produced. The temperature at which it is burnt will affect its reactivity in all other stages of the ...

High calcium quicklime, chemically known as calcium oxide (CaO), or commonly referred to as lime, is a widely used chemical compound that originates from calcium carbonate (aka limestone). Quicklime is primarily made up of calcium, magnesium and small amounts of other chemical compounds depending on the formation of the originating limestone.
