Characteristics

Raw-material oriented industry: limestone is the chief raw material (60-65%).

About 1.5 tonnes of limestone is needed for 1 tonne of cement production.

Other raw materials: clay, gypsum, coal, and fly ash.

It is a weight-losing industry, hence plants are located near limestone deposits.

Importance

Vital for infrastructure development (roads, housing, dams, bridges).

India’s cement industry provides significant employment and contributes to GDP.

Plays a key role in the growth of construction and real estate sectors.

1. What Makes a Mineral 'Critical'

High economic importance combined with high supply risk—few producing countries, geopolitical concentration, lack of substitutes, low recycling.

Ministry of Mines list (June 2023): 30 minerals including lithium, cobalt, nickel, graphite, rare earth elements, tungsten, vanadium, silicon, tin, titanium and phosphorus and potash (fertilisers).

2. Why They Matter for India

Clean-energy targets (500 GW non-fossil capacity, EV adoption) and electronics and semiconductor manufacturing depend on them.

India is heavily import-dependent for lithium, cobalt and nickel; global refining of many minerals is concentrated in China, which has used export controls (e.g. on gallium, germanium, graphite and rare earths).

3. Domestic Measures

MMDR Amendment Act, 2023: Centre can auction 24 critical and strategic minerals (Part D, First Schedule); six minerals including lithium were removed from the atomic minerals list to allow private exploration; exploration licences introduced for deep-seated minerals.

Discoveries: Lithium resources reported in Reasi (Jammu and Kashmir, 2023) and elsewhere; auctions of critical mineral blocks since 2023; offshore mineral blocks also offered.

National Critical Mineral Mission (January 2025): Exploration, mining, processing, recycling, stockpiling and overseas acquisitions.

Recycling: Battery waste management rules (2022) with EPR; incentives for recovering minerals from e-waste.

4. International Partnerships

KABIL (Khanij Bidesh India Ltd, 2019; joint venture of NALCO, HCL and MECL) acquiring lithium assets abroad, including in Argentina.

Minerals Security Partnership (US-led; India joined in 2023), partnerships with Australia, Quad critical minerals cooperation, deals with African and Latin American countries.

5. Challenges

Low exploration spending and data; long gestation of mines; lack of processing and refining technology; environmental and social impacts (forests, tribal lands); price volatility.

6. Way Forward

Invest in geoscience data and exploration, build refining capacity with technology partners, create strategic reserves, develop recycling and substitutes (e.g. sodium-ion batteries), and ensure responsible mining with community consent.

1. Energy Resources

Petroleum: Large proven reserves in Venezuela, Saudi Arabia, Iran, Canada (oil sands) and Iraq; West Asia (Persian Gulf) is the core exporting region.

Natural gas: Russia, Iran and Qatar hold the largest reserves; shale gas transformed US output.

Coal: Large reserves in the USA, Russia, Australia, China and India; China is the largest producer and consumer.

Uranium: Australia has the largest reserves; Kazakhstan is the leading producer.

2. Metallic Minerals

Iron ore: Australia and Brazil are leading producers and exporters; India, China and Russia are also major.

Bauxite: Guinea has very large reserves; Australia is a top producer; India has significant deposits in Odisha.

Copper: Chile is the largest producer, followed by Peru and the DR Congo.

3. Critical Minerals

Lithium: 'Lithium Triangle' (Chile, Argentina, Bolivia) and Australia (largest producer).

Cobalt: The Democratic Republic of the Congo produces about three-quarters of world supply.

Rare earths: China dominates mining and especially processing.

4. Water and Land Resources

Freshwater is concentrated in a few river basins and countries (Brazil, Russia, Canada); arid regions (West Asia, North Africa) face scarcity; fertile alluvial plains (Indo-Gangetic, Nile, Mississippi) support dense populations.

5. South Asia and India

India: coal (Jharkhand, Odisha, Chhattisgarh), iron ore (Odisha, Jharkhand, Chhattisgarh, Karnataka), bauxite (Odisha), mica, rare-earth-bearing monazite sands; dependent on imports for oil, gas, lithium and cobalt.

Nepal and Bhutan: hydropower potential; Bangladesh: natural gas; Pakistan: coal (Thar), gas; Afghanistan: untapped minerals.

6. Factors and Consequences

Factors: Geological history, climate, accessibility, technology, capital, political stability.

Resource curse / Dutch disease: Over-dependence on resource exports can weaken other sectors, fuel corruption and conflict (e.g. 'conflict minerals' in Central Africa); good governance (Norway's sovereign fund) can avoid it.

Geopolitics: Control of energy and critical minerals shapes alliances and trade wars.
