The extraction of iron from its ore into a workable metal is much more difficult than for copper or tin. The process appears to have been invented by the Hittites in about 1200 BC, beginning the Iron Age. The secret of extracting and working iron was a key factor in the success of the Philistines.
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.
