EXTRACTION OF IRON EXTRACTION OF IRON FROM HAEMATITEEXTRACTION OF IRON IN A BLAST FURNACE reduction

The process of the extraction of iron is carried out by the following steps Concentration of ore Calcination or Roasting of ore Reduction of ore Concentration of ore In this metallurgical operation the ore is concentrated by removing impurities like soil etc The charge is fed into the furnace from its top A preheated blast of air at 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
