The iron content in Indian iron ores is approximately _________________ percent?
Show answer Hide answer
Answer: B. 60-65
Explanation
High-grade iron ores found in India contain approximately 60 to 65 percent iron. Hematite is the primary mineral form found in these rich domestic deposits. This high iron concentration makes the ore economically viable for steel production. Iron ore is mined and processed into pig iron inside industrial blast furnaces. Ore grading determines mining extraction costs and subsequent beneficiation needs. India possesses some of the largest high-grade iron ore reserves in the world.
Steel manufacturing industries rely on consistent domestic iron ore supply chains. High iron content reduces the amount of slag-forming waste generated during smelting. Export markets value high-grade iron ore for efficient blast furnace operations. Eighty to eighty-five percent iron content exceeds natural mineral ore compositions. Forty to forty-five percent represents low-grade ores requiring extensive beneficiation. Twenty to twenty-five percent is uneconomical for direct blast furnace iron smelting.
