Quality requirements of iron ore for iron production

1/1/2015· Inside a BF, iron ore is reduced in three stages from mainly Fe 2 O 3 to Fe through Fe 3 O 4 and FeO. As mentioned earlier, there is about a 20% volume increase in the reduction of Fe 2 O 3 to Fe 3 O 4 due to the transformation of crystal lattices. However, there is negligible volume increase accompanying the reduction of Fe 3 O 4 to FeO. In fact, the volume decreases, when FeO is reduced
