Which among following processes occurs at 1500 ~K in blast furnace for extraction of iron?

Options

  1. AReduction of ore
  2. BOre loses moisture
  3. CCombustion of coke
  4. DSlag formation

Correct answer

D. Slag formation

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)
