(a) Write chemical reactions taking place in the blast furnace at reduction zone, slag formation zone and combustion zone during the extraction of Iron. |
|
Answer» SOLUTION :At reduction zone : Ferric oxide is reduced to iron CARBON monoxide `Fe_(2)O_(3)+3COoverset(600-700^(@)C)rarr2Fe+3CO_(2)` Slag formation zone : Limestone decomposes to form calcium oxide, which then combines with silica to form calcium silicate slag `CaCO_(3)overset(900^(@)C)rarrCaO+CO_(2)` `CaO+SiO_(2)rarrCaSiO_(3)` Calcium Silicate (slag) Combustion Zone : Coke burns in oxygen to form carbon DIOXIDE. `C+O_(2)overset(1500^(@)C)rarrCO_(2)` |
