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
