    2013-1-1 · In the CFB reactor, preheated iron ore is pre-reduced to a degree of metallisation of up to 85% with CO and H 2 out of in situ coal gasification. The reactor off gas is used in one or two preheating stages (depending on desired off gas temperature) to preheat the cold iron ore making use of the sensitive heat in the gas.

  • Iron ore BHP

    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. The ships we use to transport iron ore to our customers can carry around 47 Olympic-sized swimming pools worth of material.
