Blast furnace formula basics

Raw materials

Coke = Carbon (C)

Iron ore (haematite) = Iron oxide = Fe2O3 (Press here to remember this formula)


Reaction basics

Iron ore + Carbon monoxide       →           Iron + Carbon dioxide

Fe2O3 + CO                                     →           Fe + CO2


This is not balanced. Can we balance it?

Putting a 3 in front of the carbon monoxide and carbon dioxide will balance both the carbon and oxygen on each side of the equation.

Fe2O3 + 3CO       →           Fe + 3CO2

Then, we need to balance the iron by adding a 2.

Fe2O3 + 3CO       →           2Fe + 3CO2
