caco3 from limestone process
Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.

Lime Processes – Alpha Thermal Process
Lime Processes. The dissociation of limestone (calcium carbonate) into quicklime and carbon dioxide at temperature is a process known as calcination i.e., CaCO 3 = CaO + CO 2 ΔH = -760 BTU/lb CaCO 3. Magnesium Carbonate, which is found in some quantities with limestone deposits, also dissociates according to the reaction: MgCO 3 = MgO + CO 2

The Calcium Looping process for energy storage: Insights from in situ
The CaCO 3 structure formed in the first step of dolomite decomposition has smaller unit cell volume than the CaCO 3 naturally present in limestone. The CaO that stems from decomposition of the CaCO 3 derived from dolomite first decomposition shows a greater carbonation reactivity compared to the CaO derived from limestone.
