Correct answer: A. Hot metal
- A. Hot metal
- B. Flue gases
- C. Slag
- D. Refractory lining
Explanation
Phosphorus is readily reduced and dissolves in the molten iron, so most of it reports to the hot metal in the blast furnace. Unlike sulphur, it is not normally removed mainly into the slag under ordinary blast-furnace conditions.
