Extraction of iron from its oxide and it's equation?

Fe₂O₃ is reduced in blast furnaces using CO to form Fe through the calcination process.
Equation: Fe₂O₃ + 3CO  2Fe + 3CO₂

 

Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.

 

Equation :-  Iron(III) oxide + carbon → iron + carbon dioxide
