Carbon Reducing Iron Oxide in Blast Furnace

2Fe2O3 + 3C → 4Fe + 3CO2

Aperçu

Carbon (from coke) reduces iron(III) oxide to produce iron metal and carbon dioxide. This is the simplified overall reaction in a blast furnace. In practice, carbon monoxide does most of the reduction work at intermediate temperatures in the furnace stack.
