The composition of iron ore playsan important role in both the iron (blast,EXTRACTION OF IRON IN A BLAST FURNACE reduction,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. Haematite is added to the top of the furnace along with coke (i.e. carbon) and limestone. Three reactions take place during this extraction.
