What is the process of extracting iron from its ore? Iron is extracted from iron ore in a huge container called a blast furnace. In this reaction, the iron(III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide. Why is carbon used to extract iron? This method of extraction works because carbon is more reactive than iron
