Extraction of Iron from Haematite Grade 12 Science Notes

The slag is lighter than molten iron and to floats on the surface of the iron. The formation of prevents the oxidation of iron. d. Zone of Reduction:-This is the most important zone and has temperature of 600-700 0 c. In this zone Fe 2 O 3 is reduced to iron by co in three steps. 3Fe 2 O 3 + CO → 2Fe 3 O 4 + CO 2

EXTRACTION OF IRON IN A BLAST FURNACE reduction

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.

GCSE CHEMISTRY Extraction of Iron Haematite

Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.
