Which of the following ores is primarily an oxide ore of iron?

💡 Solution & Explanation

Hematite is a prominent oxide ore of iron with the chemical formula Fe2O3, serving as a primary raw material in global steel manufacturing industries. Other options like chalcopyrite and cinnabar represent copper and mercury sulfide minerals respectively, whereas galena is a lead sulfide compound. Metallurgical extraction processes utilize reduction techniques inside blast furnaces to separate pure metal from these oxide ores.
