Question
Which reducing agents are used to reduce haematite ore into metallic iron?
✓

Answer

Haematite ore is reduced using coke and CO. Carbon in the coke is converted to carbon monoxide. Carbon and carbon monoxide together reduce $Fe 203$ to metallic iron.
$\begin{aligned}
& Fe _2 O _3+3 C \rightarrow 2 Fe +3 CO \\
& Fe _2 O _3+3 CO \rightarrow 2 Fe +3 CO _2
\end{aligned}$
