Extraction
of iron is based on the reduction of Haematite ()
with carbon.
The
process of the extraction of iron is carried out by the following steps:
1)
Concentration of ore
2) Calcination or Roasting of ore
3)
Reduction of ore
Reduction of ore:
The blast oxidizes carbon to .
.
Formation
of CO2 is an exothermic reaction in which a huge amount of heat
is liberated which rises the temperature to 1900OC
in this region. As the passes upwards, it reacts more coke
to form carbon monoxide..
Reactions
in blast furnace;
Overall
reaction ;..
Slag
formation:..
.
So the reactions in the options A,B are not preesent
Hence options C, D are correct.
