1.	Which among the following is an essential chemical reaction for the manufacture of pig iron?(a) Fe2O3 + 3C → 2Fe + 3CO(b) FeS + C → Fe + CS(c) Fe3O4 + S → 3Fe + SO4(d) Fe2O3 + S → 2Fe + SO3This question was posed to me by my college director while I was bunking the class.Question is taken from Iron topic in division Metallurgical Industries of Chemical Technology
Answer» CORRECT answer is (a) Fe2O3 + 3C → 2Fe + 3CO The BEST I can explain: Coke is REACTED with hematite at a high TEMPERATURE through a furnace. As air reacts with coke CO and heat is generated as iron oxide is REDUCED, molten iron gathers at the base of the furnace.
