Mineral Resources — Iron and Manganese

3 min read indian-geography minerals iron-ore manganese

India is richly endowed with mineral resources, especially in the Peninsular shield region. The country is among the world’s top 5 producers of most metallic minerals.

Iron Ore — The Backbone of Industry

India is the world’s 4th largest iron ore producer (~255 MT annually) with ~33% of the world’s iron ore reserves in terms of iron content.

Types of Iron Ore

Type Iron Content Color Distribution
Hematite (Fe₂O₃) 60-70% Reddish Major ore for steel-making; Odisha, Jharkhand, Chhattisgarh
Magnetite (Fe₃O₄) 60-70% Black Higher quality but less accessible; Karnataka, Tamil Nadu, Goa
Limonite (Hydrated Fe₂O₃) 35-50% Yellow-brown Low grade; scattered deposits
Siderite (FeCO₃) 30-45% Grey-green Very limited

Major Iron Ore Belts

Belt States Ore Type Major Mines
Odisha-Jharkhand Odisha, Jharkhand Hematite Keonjhar: Taldih, Gandhamardan; Sundargarh: Barsua, Koira; Mayurbhanj: Badampahar, Sulaipat, Gorumahisani
Chhattisgarh Chhattisgarh, MP Hematite Bailadila (Dantewada) — world’s richest mines (68% Fe); Dalli-Rajhara (Durg)
Karnataka-Goa Karnataka, Goa Hematite & Magnetite Kudremukh (magnetite; now closed for conservation); Ballari-Hospet belt; Goa belt (now mining restricted)

Production Share

State Share Grade
Odisha ~55% 62-66% Fe
Chhattisgarh ~15% Highest grade (Bailadila 67-68% Fe)
Karnataka ~12% Mixed
Jharkhand ~10% Good grade
Goa ~5% Low grade (55-58% Fe); mostly exported

Exports and Imports

  • Major export destinations: China, Japan, South Korea
  • Impact: Iron ore prices and export policy have been politically contentious
  • 2018 SC verdict: Mining restrictions in Goa, Odisha, Karnataka have impacted production

Manganese

India is the 5th largest producer of manganese ore in the world, with production of about 3.5 million tonnes annually. Manganese is essential for steel-making (as a deoxidizer and alloying agent) and dry battery cells.

Distribution

State Share Key Mines
Odisha ~35% Keonjhar — Jajangu, Belkundi, Bichaburu; Sundargarh; Kalahandi — Ormoguda, Kutingia
Karnataka ~20% Shimoga — Kumsi, Kamenahalli; Chitradurga — Hirehalla, Sangli; Bellary, Tumkur
Madhya Pradesh ~15% Balaghat — Ukwa, Tirodi, Mansar; Chhindwara, Jabalpur
Maharashtra ~10% Nagpur (Mansar); Bhandara
Goa ~5% Secondary product of iron ore mining

Ore Grades

Grade Manganese Content Uses
Metallurgical 50%+ Mn Steel-making and ferro-alloys
Battery grade 80%+ MnO₂ Dry cell batteries
Chemical grade Variable Glass, ceramics, pigments, fertilizers

Key Issues in Indian Mining

Issue Description
Illegal mining Major scandal in Karnataka (Bellary) and Odisha — reports of rampant illegal extraction
Environmental damage Deforestation, water pollution, loss of biodiversity; Kudremukh and certain Goa mines closed for conservation
Tribal displacement Most mines located in tribal belts — displacement and rehabilitation persistent issues
Export policy Fluctuating export duties; court orders restricting mining in key states
Value addition India exports significant low-grade ore but imports high-grade steel — lost value-adding opportunity

Mineral Rights and Regulatory Framework

  • Mines and Minerals (Development and Regulation) Act, 1957 — principal legislation
  • 2015 Amendment: Auction-based allocation of mines; right of first refusal for existing lessees
  • Mineral Conservation and Development Rules, 2017
  • District Mineral Foundation (DMF): 30% of royalty paid into DMF for local area development
  • National Mineral Policy 2019: Focus on zero-waste mining, sustainable practices, transparency

Major Mining Companies

  • NMDC Limited (National Mineral Development Corp.) — India’s largest iron ore producer
  • SAIL (Steel Authority of India) — captive mines in Odisha, Jharkhand, Chhattisgarh
  • Vedanta Resources — Goa iron ore, Balco, HZL
  • MOIL (Manganese Ore India Ltd.) — largest manganese producer; Odisha, MP, Maharashtra
