Which element is removed from iron in the Bessemer process or basic oxygen steelmaking to convert it into steel?
Correct answer: C. Carbon
- A. Silicon
- B. Sulfur
- C. Carbon
- D. Phosphorus
Explanation
The main goal of steelmaking is to reduce the high carbon content of pig iron (typically 4-5%) to a much lower level (usually less than 2%). Oxygen is blown through the molten iron to oxidize the excess carbon into gaseous carbon oxides.
