Metallic Minerals of India

Prerequisites

• Physiography of India: the Peninsular plateau and its old crystalline rocks, where almost all metallic minerals are found.
• Mineral Resources and Mining Belts of Chhattisgarh: the state-level version of this page. Read the two together.

The Hook: From Bailadila to Visakhapatnam

Why it matters: Prelims P-I asks “which state leads in X”, “where is mine Y” and which ore of iron is richest. Mains P-V GS-III asks about the distribution of minerals and about mining-led development, where you can bring in Chhattisgarh.

Classifying Minerals

A mineral (खनिज) is a naturally occurring, homogeneous substance with a definite chemical composition. A mineral from which a metal can be extracted profitably is an ore (अयस्क).

Non-metallic and energy minerals are covered in Non-metallic Minerals and Conventional Energy.

The geological rule

Since the Peninsula is old and stable, NCERT notes that most major mineral resources lie to the east of a line linking Mangaluru and Kanpur. The Indo-Gangetic plain, made of recent alluvium, has almost none.

Mineral belts of India

Chhattisgarh lies at the heart of the north-eastern belt, which explains its coal, iron ore, bauxite and tin.

Ferrous Minerals

Iron ore (लौह अयस्क)

Production: India mined about 274 million tonnes of iron ore in FY 2023-24 (Ministry of Mines). Odisha produces more than half. Karnataka, Chhattisgarh and Jharkhand follow, and their order changes from year to year.

Manganese (मैंगनीज़)

• Used mainly to make steel and ferro-manganese. NCERT notes that about 10 kg of manganese goes into one tonne of steel. Also used in bleaching powder, insecticides and paints.
• Odisha has the largest resources. Production comes mainly from Madhya Pradesh (Balaghat), Maharashtra (Nagpur, Bhandara) and Odisha (Kendujhar, Sundargarh). Madhya Pradesh led production in 2020-21 and 2021-22 (IBM), but the lead changes between these three states.
• MOIL Ltd, a central PSU headquartered at Nagpur, is the largest producer.

Chromite (क्रोमाइट)

• Odisha has almost all of India’s chromite resources and production, concentrated in the Sukinda valley (Jajpur) and Kendujhar. Minor deposits occur in Karnataka (Hassan), Manipur and Nagaland.
• Used for stainless steel (ferro-chrome), refractories and chemicals.
• The overburden at Sukinda also contains nickel.

Non-ferrous Minerals

Bauxite (बॉक्साइट): the ore of aluminium

• Formed by the weathering of rocks rich in aluminium silicates into laterite in hot, wet climates. It is found on flat-topped plateaus.
• Odisha leads in both resources and production. The Panchpatmali deposit in Koraput feeds NALCO (National Aluminium Company, Bhubaneswar).
• Other areas: Jharkhand (Lohardaga), Gujarat (Jamnagar, Bhavnagar), Maharashtra (Kolhapur), Chhattisgarh (Mainpat in Surguja, and the Maikal hills of Kabirdham), Madhya Pradesh (Katni, Amarkantak plateau).
• BALCO at Korba (Chhattisgarh) is one of India’s oldest aluminium smelters. See Major Industries and Steel.

Copper (तांबा)

India is deficient in copper and imports a large part of its needs. Copper is essential to electrical cables, electronics and electric vehicles.

Lead and zinc (सीसा और जस्ता)

• Rajasthan produces almost all of India’s lead and zinc, from the Aravallis: Rampura Agucha (Bhilwara), Zawar (Udaipur), Sindesar Khurd (Rajsamand).
• They are mined by Hindustan Zinc Ltd (HZL), majority-owned by Vedanta since its disinvestment in the early 2000s. Silver is recovered as a by-product, which makes Rajasthan India’s main silver source.
• Uses: zinc for galvanising steel, lead for batteries.

Tin and tungsten

• Tin (टिन): Chhattisgarh (Dantewada) is the only tin-producing state, from cassiterite. Haryana (Tosham) has larger resources but no production.
• Tungsten: Degana (Nagaur, Rajasthan) is the best-known deposit.

Precious Metals

India’s own gold output is tiny compared with its consumption, so gold is one of its largest imports.

Analysis for Mains: Why Mineral Wealth Has Not Meant Prosperity

1. Concentration: Most metallic minerals are in Odisha, Jharkhand, Chhattisgarh and Karnataka. These states are mineral-rich, but large parts of their mining districts are tribal and poor. This mismatch is often called the “resource curse”.
2. Value addition: Raw ore is exported or moved out of the state. More beneficiation, pelletisation and steelmaking near the mine would keep more value local.
3. Governance reforms: The MMDR Amendment Act, 2015 made auction compulsory for new mineral concessions and created the District Mineral Foundation (DMF) and the National Mineral Exploration Trust. See Non-metallic Minerals for the full policy picture.
4. Environment and rights: Mining in forested Scheduled Areas raises issues of displacement, forest loss and Gram Sabha consent under PESA and the Forest Rights Act.
5. Strategic gaps: India is self-sufficient in iron ore, bauxite and chromite but import-dependent in copper, gold, nickel, cobalt and lithium.

Chhattisgarh angle: Bailadila, Dalli-Rajhara, Mainpat and Dantewada tin show the whole debate in one state. The second-generation question is whether DMF funds reach the villages around the mines.
