The main reaction occuring in blast furnance during extraction of iron from haematite ore …..

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)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
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).
