Vedclass · Answer

(A) In the blast furnace,limestone $(CaCO_3)$ is added as a flux. It decomposes to form calcium oxide $(CaO)$.$CaCO_3 \rightarrow CaO + CO_2$The calcium oxide $(CaO)$ reacts with the silica $(SiO_2)$ impurity present in the ore to form molten calcium silicate $(CaSiO_3)$,which is known as slag.$CaO + SiO_2 \rightarrow CaSiO_3$ (Slag)Therefore,the correct answer is calcium silicate.

During the extraction of iron from hematite in a blast furnace,which substance is obtained as slag?
