The Blast Furnace

• What materials are found in a blast furnace?

  Iron Ore

  Limestone

  Coke (Carbon)

  Oxygen
• What is the process of the blast furnace?

  Oxygen from the hot air reacts with the coke to form to form carbon monoxide

  Carbon monoxide reacts with iron (III) oxide to give iron

  Limestone undergoes thermal decomposition to form calcium oxide

  Calcium reacts with silicon oxide (sand) to form slag
• What type of reaction takes place in the blast furnace?

  Neutralisation Reaction
• What is the function of the blast furnace?

  To obtain pure iron from iron oxide compounds
