Sep 06, 2019To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. The calcium in limestone bonds with the silicates in the ore, creating a material called slag, which floats on top of the pure liquid iron. The iron is periodically drained into a mold from a port at the bottom of the blast furnace, where it cools.
