  • Ironmaking 101 – From Ore to Iron with Blast Furnaces ...

    Oct 10, 2017  Ironmaking Blast Furnace Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.

  • Iron Extraction by Blast Furnace Metallurgy - Procedure ...

    Jun 29, 2020  Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.
