Vedclass · Answer

(B) In the extraction of iron from its ore (hematite,$Fe_2O_3$),limestone $(CaCO_3)$ is added as a flux. This flux reacts with the silica $(SiO_2)$ impurity present in the ore to form calcium silicate $(CaSiO_3)$,which is known as slag. $CaO + SiO_2 \rightarrow CaSiO_3$ (Slag). Slag is a molten byproduct that floats on top of the molten iron and is removed separately.
