# Write the Reactions Involved in the Zone of Reduction in Blast Furnace During Extraction of Iron. - Chemistry

Write the reactions involved in the zone of reduction in blast furnace during extraction of iron.

#### Solution

Zone of reduction:-
Carbon monoxide reduces ferric oxide to spongy iron (porous solid) at about 900 K.
$\ce{3Fe^2O^3 + CO -> 2Fe^3O^4 + CO^2}$
$\ce{Fe^3O^4 + 4CO -> 3Fe + 4CO^2}$
$\ce{Fe^2O^3 + CO -> 2FeO + CO^2}$

Concept: Occurrence of Metals
