Vedclass · Answer

(B) In the blast furnace,the extraction of iron involves different temperature zones. At the zone of slag formation (approx. $1073-1273 \ K$),the limestone $(CaCO_3)$ decomposes to $CaO$. This $CaO$ acts as a flux and reacts with the silica $(SiO_2)$ impurity present in the ore to form calcium silicate,which is the slag. The reaction is: $CaO + SiO_2 \longrightarrow CaSiO_3 	ext{ (slag)}$.

Which among the following reactions occurs at the zone of slag formation in the extraction of iron by a blast furnace?
