Consider the following statements regarding the extraction of iron from Haematite ore: 1. Haematite (Fe2O3) is concentrated primarily by gravity separation (hydraulic washing) due to the difference in density between ore and gangue. 2. In the blast furnace, carbon monoxide (CO) acts as the primary reducing agent at lower temperature zones. 3. Pig iron obtained from the blast furnace is the purest form of commercial iron. Which of the statements given above are correct?

Options:

• A: 1 and 2 only
• B: 2 and 3 only
• C: 1 and 3 only
• D: 1, 2 and 3
