Which of the following process involves smelting?

Options

  1. AZ n C O 3 → Δ Z n O + C O 2
  2. BF e 2 O 3 + 3 C → H e a t 2 F e + 3 C O
  3. C2 P b S + 3 O 2 → H e a t 2 P b O + 2 S O 2
  4. DA l 2 O 3 . 2 H 2 O → H e a t A l 2 O 3 + 2 H 2 O

Correct answer

B. F e 2 O 3 + 3 C → H e a t 2 F e + 3 C O

Step-by-step solution

We know that smelting is reduction with carbon. Here Fe 2 O 3 with the help of carbon.
