Iron Extraction by Blast Furnace Metallurgy - Procedure ...

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.
