Iron Smelting Essential Humanities
Rock that is rich in a valuable mineral is referred to as ore. Most iron ore contains some form of iron oxide e.g. Fe 2 O 3, Fe 3 O 4. 3 In order to extract iron from iron ore, one must first remove the unwanted minerals, then remove the oxygen from the iron. The latter step can only be achieved with a chemical reaction.
