The main ores of iron:
Ore Name | Chemical Composition | Iron Content | Color | Key Characteristics | Found In (India) | Uses |
|---|---|---|---|---|---|---|
Hematite | Fe₂O₃ | ~69% | Reddish-brown | High-grade ore; most important source of iron. | Odisha, Jharkhand, Chhattisgarh, Karnataka | Steelmaking |
Magnetite | Fe₃O₄ | ~72% | Black or dark brown | Richest in iron content; magnetic properties. | Tamil Nadu, Karnataka, Andhra Pradesh, Goa | Steelmaking, coal washing |
Limonite | Fe₂O₃·nH₂O | 40-60% | Yellowish-brown to dark brown | Formed by weathering of hematite and magnetite. | Jharkhand, Goa, Maharashtra | Pigments, secondary source of iron |
Siderite | FeCO₃ | ~48% | Yellowish to brownish-grey | Low-grade ore; often mixed with impurities. | Bihar, Madhya Pradesh | Lesser use due to low iron content |
Goethite | FeO(OH) | ~62% | Brown, yellow, or orange | Found as weathered deposits; moderately rich. | Odisha, Jharkhand, Goa | Steelmaking, pigments |
