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

Options

  1. AC + 1 2 O ₂ CO
  2. BCaO + SiO ₂ CaSiO ₃
  3. CFe ₂ O ₃+3 CO 2 Fe +3 CO ₂
  4. DFe ₂ O ₃+3 C 2 Fe +3 CO

Correct answer

B. CaO + SiO ₂ CaSiO ₃

Step-by-step solution

The slag formed in the extraction of iron from haematite in the blast furnace is CaSiO ₃ . The reaction in the blast furnace is as follows: CaO + SiO ₂ CaSiO ₃ (slag)
