Iron Extraction Manufacturing Process - Blast Furnace Method

Fe 2 O 3 is reduced to iron mainly by carbon monoxide and to some extent by coke. Reactions of iron extraction Fe 2 O 3 reduction to iron is done step by step. Temperature variation along the blast furnace will help to occur these reactions. Now, we can study what are the reactions occurring inside the blast furnace at different temperatures.
