Question

With respect to the reduction of iron ore in the blast furnace, answer the following questions:

Name the raw material placed in the blast furnace.

Answer 1

• The reduction of oxide to metal is carried out in the presence of carbon in a blast furnace by the process called smelting.
• In the blast furnace, the iron ore i.e. Haematite (${\mathrm{Fe}}_2{\mathrm{O}}_3$) is mixed with coke$\left(\mathrm{C}\right)$ and limestone or Calcium carbonate$\left({\mathrm{CaCO}}_3\right)$ approximately in the ratio $8:4:1$.

Hence, iron ore, coke, and limestone are the raw materials placed in the blast furnace.
