Which among following processes occurs at \(1500 \mathrm{~K}\) in blast furnace for extraction of iron?
- A Reduction of ore
- B Ore loses moisture
- C Combustion of coke
- D Slag formation
Answer & Solution
Correct Answer
(D) Slag formation
Step-by-step Solution
Detailed explanation
The slag formed in the extraction of iron from haematite in the blast furnace is \(\mathrm{CaSiO}_{3}\). The reaction in the blast furnace is as follows:
\(\mathrm{CaO}+\mathrm{SiO}_{2} \rightarrow \mathrm{CaSiO}_{3} \text { (slag) }\)
\(\mathrm{CaO}+\mathrm{SiO}_{2} \rightarrow \mathrm{CaSiO}_{3} \text { (slag) }\)
