## HOW TO CALCULATE EFFICIENCY OF YOUR LIME BURNING

This conversion of calcium carbonate to calcium oxide is achieved by heating the limestone to a temperature high enough (e.g. 1000 C in a lime kiln) to 'drive off' carbon dioxide, CO 2. The equation for this process, with the approximate molecular weights, is: 100 CaCO 3 + Heat 56 CaO + 44 CO 2 Continuing the approximation for hydration gives:

## Calcination - Wikipedia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.

## Precipitated Calcium Carbonate (PCC) | Minerals ...

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate

## Calcium carbonate - Essential Chemical Industry

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
