EXTRACTION OF IRON IN A BLAST FURNACE reduction haematite O
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.

Iron removal by physical chemical way - Lenntech
Pourbaix diagram of Iron. However ground waters are naturally anaerobic: so iron remains in solution and therefore it is important to remove it for a water use. The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation.
