In extraction of iron the changes taking place in the blast furnace is

$ (a)\;\text{Oxidation of the sulphide ore.} \\(b)\;\text{Sulphide reduction to metal} \\(c)\;\text{Oxide reduction to metal} \\ (d)\;\text{Reduction of the sulphide ore.} $

1 Answer

Explanation: oxide ores of iron after concentration through calcination/roasting (to remove water,to, decompose carbonates and to oxidise sulphides) are mixed with limestone and coke and fed into a Blast furnace from its top.
Here, the oxide is reduced to the metal.
Hence c is the correct answer.
