The main reaction occuring in blast furnace during the extraction of iron form haematite is

Options

A. `Fe_(2)O_(3)+ 3CO to 2Fe+3CO_(2)`
B. `FeO +SiO_(2) to FeSiO_(3)`
C. `Fe_(2)O_(3)+C to 2Fe+3CO`
D. `CaO+SiO_(2) to CaSiO_(3)`

Answer

A, D

Explanation

In extraction of `Fe,Fe_(2)O_(3)` is primary reduced by CO below `710^(@)C` and acidic impurity of `SiO_(2)` is removed is the form of `CaSiO_(3)` (slag).
