    The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

  • Mining Of Iron Ore Oxide

    To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted. Approximately two billion tonnes of iron ore are mined each year.
