Solution
In the extraction of iron, a basic flux limestone is used. Limestone decomposes to form CaO which reacts with silica gangue present in the iron ore is acidic in nature to form calcium silicate (slag).
\[\ce{CaCO3 -> CaO + CO2}\]
\[\ce{\underset{\text{Flux}}{CaO} + \underset{\text{Gangue}}{SiO2} -> \underset{\text{Slag}}{CaSiO3}}\]
