(D) During the extraction of iron from haematite ore $(Fe_2O_3)$,the roasted ore is mixed with coke and limestone and heated in a blast furnace.Coke acts as a reducing agent to reduce iron oxides to metallic iron.Limestone $(CaCO_3)$ decomposes to form calcium oxide $(CaO)$,which acts as a flux.This flux reacts with acidic impurities like silica $(SiO_2)$ present in the ore to form calcium silicate $(CaSiO_3)$,which is known as slag.Therefore,the role of limestone is to act as a flux.
