Iron is obtained on large scale from haematite `Fe_(2)O_(3)`

Options

A. by reduction
B. by oxidation
C. by reduction followed by oxidation
D. by oxidation followed by reduction

Answer

A

Explanation

In the zone of reduction of blast furnace, reduction of `Fe_(2)O_(3)` occurs by CO.
`3Fe_(2)O_(3)+CO overset(Delta)to 2Fe_(3)O_(4)+CO_(2) underset(Delta)overset(CO)to 6FeO+3CO_(2)`
`Fe_(2)O_(3)+CO overset(Delta)to2FeO+CO_(2) overset(CO)to 2Fe+2CO_(2)`
