# What redox reactions occur in an iron foundry?

May 20, 2016

(i) oxidation of carbon and carbon monoxide to carbon dioxide; (ii) reduction of ferric oxide to iron.

#### Explanation:

$\text{Oxidation}$

$C \left(s\right) + \frac{1}{2} {O}_{2} \left(g\right) \rightarrow C O \left(g\right)$

$\text{Reduction}$

$F {e}_{2} {O}_{3} \left(s\right) + 3 C O \left(g\right) \rightarrow 2 F e \left(l\right) + 3 C {O}_{2} \left(g\right)$

If you ever have the opportunity to visit a working blast furnace, where hot gases are blasted thru a pile of coke and ore to give iron, do so. You feel very small given the size and sound of the furnace.
