  • Iron ore BHP

    It takes around 1.6 tons of iron ore to produce one ton of steel. The chemical symbol for iron is 'Fe' because of its Latin name Ferrum. We use 20 times more iron (in the form of steel) than all other metals put together. Our iron ore trains are over 2.5km (264 ore cars) long, meaning it can take half an hour from one end to the other.
