EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.
May 22, 2009 People discovered that a high temperature coal fire could be used for the extraction of iron from iron ore. The discovery of electricity at the beginning of the nineteenth century allowed the extraction of the more reactive metals. Aluminium has been extracted on a large scale since about 1870. 4.
