The main reactions occurring in blast furnace during extraction of iron from
haematite are ________.
Reduction of iron oxides to iron happens at a blast furnace
Fe2O3 + CO → 2FeO + CO2
2FeO + 2CO →2Fe + 2CO2
-------------------------------
Fe2O3 + 3CO → 2Fe + 3CO2overall reaction
----------------------------------------------
The other reaction that happens is the slag formation,
CaO + SiO2→ CaSiO3(slag)
