The flux used in the preparation of wrought iron from cast iron in reverberatory furnace is
- A \(\mathrm{SiO}_2\)
- B \(\mathrm{CaCO}_3\)
- C C
- D NaCN
Answer & Solution
Correct Answer
(B) \(\mathrm{CaCO}_3\)
Step-by-step Solution
Detailed explanation
\(\mathrm{Fe}_2 \mathrm{O}_3+3 \dot{\mathrm{C}} \longrightarrow 2 \mathrm{Fe}+3 \mathrm{CO}\) Lime stone \(\left(\mathrm{CaCO}_3\right)\) is added as a flux and sulphur, silicon and phosphorus are oxidixed and passed into the slag.
