Iron Ore In Limestone

How iron is made

The ingredients to make useable iron were limestone ironstone coke and air The coke is the fuel and the ironstone provides the iron ore Ironstone is first roasted in calcining kilns located next to the blast furnaces to remove impurities The air or blast was blown into the blast furnace by powerful steam engines They used cold air until 1828 when it was discovered at Wilsontown that
