Ten Times by 2047: India's Critical Minerals Gap Is a Processing Problem, Not a Mining One
Summary
A Grant Thornton Bharat report released on 30 July 2026 projects that India's demand for critical minerals and rare earth elements could rise four to ten times by 2047, and warns that the country's advanced manufacturing ambitions could be constrained unless capability is built beyond mining.
●India's policy response is the National Critical Mineral Mission, launched in 2025, under which the Geological Survey of India is to conduct 1,200 exploration projects between 2024-25 and 2030-31.
●A Ministry of Mines committee constituted in November 2022 identified 30 critical minerals, of which 24 were placed in Part D of the First Schedule of the Mines and Minerals (Development and Regulation) Act, 1957, giving the Central Government exclusive authority to auction their mining leases and composite licences.
●The demand is driven by clean energy: silicon, tellurium, indium and gallium for solar photovoltaics, and dysprosium and neodymium for the permanent magnets in wind turbines and electric vehicles.
Core Arguments
- 1
The strategic vulnerability lies in midstream processing, not upstream extraction. Rare earth ores are geologically common — India holds among the world's larger monazite reserves — but separating individual rare earths from one another is chemically difficult, capital-intensive and environmentally burdensome, and that capacity is concentrated in very few countries. Exploration without refining reproduces dependence in a new form.
- 2
The Part D reallocation is a federal choice with real consequences. Moving auction authority for 24 minerals to the Centre enables a coherent national strategy and prevents States from competing down terms, but it reduces State revenue autonomy over resources located within their territory, which is a live grievance in mineral-bearing States and a recurring theme in Indian fiscal federalism.
- 3
Recycling deserves the weight the mission gives it. Urban mining of end-of-life electronics, batteries and magnets can supply a meaningful share of demand for several critical minerals without new extraction, and it substitutes domestic material flows for imports. India's e-waste is largely handled by the informal sector, so formalising and upgrading that chain is a supply-security measure as much as an environmental one.

Demand-side substitution is an underused lever. Motor designs that reduce or eliminate rare earth magnets, sodium-ion chemistries that avoid lithium and cobalt, and thin-film photovoltaics with different material bases all reduce exposure. Research funding that lowers material intensity can deliver supply security more cheaply than securing the material itself.

The projection itself should be read with care. A four-to-ten-times range by 2047 is a very wide band, reflecting genuine uncertainty about technology paths, and planning capacity to the top of that range risks overbuilding while planning to the bottom risks shortage. The honest policy response is optionality — flexible contracts, diversified sourcing and strategic stockpiles — rather than a single-point demand forecast.
Dimensional Angles
Economic
Critical mineral dependence transmits directly into India's manufacturing ambitions. Production-linked incentives for electronics, batteries and solar assume input availability at predictable prices, and an input whose supply can be curtailed by a single exporting country undermines the entire incentive structure. The cost of building domestic processing is high, but the relevant comparison is against the option value of not having production halted.
International Relations
Mineral supply has become an explicit instrument of statecraft, with export licensing used to apply pressure on downstream manufacturing elsewhere. India's response has combined domestic capability with plurilateral arrangements and bilateral partnerships, including a critical minerals agreement with the United States, and overseas asset acquisition through state-backed entities. Diversification of sourcing is the practical objective, since autarky in these minerals is not achievable.
Environmental
Critical mineral extraction and especially rare earth separation generate substantial waste, including radioactive residues from monazite processing given its thorium content. Scaling domestic capacity therefore imports an environmental burden that has partly been offshored, and the regulatory question is whether India's environmental appraisal and waste-management capacity scale alongside its processing ambitions.
Science & Technology
Separation chemistry is the technical crux. Rare earths occur together and have very similar chemical behaviour, so separating them requires many stages of solvent extraction, a process where operational know-how matters as much as capital. This is why technology partnerships and personnel training, rather than plant purchase alone, determine whether a country can move from ore to usable oxide.

Data: Grant Thornton Bharat (30 July 2026): India's demand for critical minerals and rare earth elements could increase four to ten times by 2047, with advanced manufacturing constrained unless capability is built beyond mining.
- ◆
Data: Press Information Bureau on the National Critical Mineral Mission: the Geological Survey of India is tasked with 1,200 exploration projects between 2024-25 and 2030-31, and 24 of 30 identified critical minerals sit in Part D of the First Schedule of the MMDR Act, 1957.
- ◆
Comparison: India aims to raise wind capacity from 42 GW to 140 GW by 2030 while solar capacity stood at 64 GW — both trajectories depend on minerals India currently imports in processed form, which is why demand growth is a supply-security question rather than a mining one.
- ◆
Concept: In critical mineral supply chains the chokepoint is midstream. Ore is geologically widespread, but separation and refining capacity is concentrated, so a country can hold substantial reserves and remain entirely dependent on others to make them usable.
