Question

The main reaction occuring in blast furnace during the extraction of iron form haematite is
A. `Fe_(2)O_(3)+3CO to 2Fe+3CO_(2)`
B. `FeO+SiO_(2) to FeSiO_(3)`
C. `Fe_(2)O_(3)+3C to 2 Fe +3CO`
D. `CaO+SiO_(2) to CaSiO_(3)`

Answer 1

Correct Answer - A::D
(a,d) In extraction of iron from haematite ore following reactions take place.
(i) `Fe_(2)O_(3) to 2Fe+3CO_(2)`
This reaction represent reduction of `Fe_(2)O_(3)` to Fe.
(ii) ` underset("Formation of slang ")(CaO+SiO_(2)) to underset ("Slag")(CaSiO_(3))`
