What is the role of lime or limestone in the extraction of …
The chemical formula of limestone is CaCO 3. Limestone is a basic flux that can be used to form fusible slag from earthly impurities present in the ore. Limestone undergoes decomposition to form lime i.e. Calcium oxide (CaO) and Carbon dioxide. The decomposition reaction occurs as follows: CaCO 3 s Limestone → CaO s (Lime) + CO 2 g

Limestone: The Calcium Carbonate Chemical Sedimentary Rock
Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3 ). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it …
