The critical raw materials value chain: why the chokepoint is not at the mine

The public conversation about critical raw materials is dominated by mines. New projects make headlines, permitting disputes attract political attention, and strategic ambitions are routinely expressed in terms of where new extraction will happen. This is understandable. Mining is visible, tangible, and politically consequential in a way that the rest of the value chain rarely is.

It is also a distraction from the binding constraint.

For most critical raw materials, the most consequential bottleneck in the global supply chain does not sit at the mine. It sits downstream, in the processing and refining stages, where ore is transformed into the materials that actually enter industrial use. The Payne Institute for Public Policy at Colorado School of Mines put the point directly in its 2025 State of Critical Minerals Report: China's dominant market share downstream of mining, specifically in refining and processing, is what creates the most acute vulnerability for Western economies. The European Court of Auditors reached the same conclusion in its February 2026 assessment of EU policy, noting that 100% of rare earth processing currently takes place outside the European Union and that domestic processing capacity is in some areas shrinking rather than growing.

Both assessments point to the same underlying reality. A mining-first framing of supply security obscures where the leverage actually sits. Until that framing shifts, investment at one end of the chain will continue to generate dependency at the other.

The critical raw materials value chain does not behave like a chain

The critical raw materials chokepoint.

Critical raw materials value chains comprise six recognisable stages: exploration, extraction, processing, refining, manufacturing, and recycling. Presented sequentially, they look like a linear progression from geology to finished product. In practice, they do not behave that way. Concentration, capital intensity, technical complexity, and regulatory exposure vary dramatically across stages, and the interactions between stages frequently matter more than the characteristics of any single one.

For exploration and extraction, geological endowment imposes meaningful constraints, but in a less binding way than is often assumed. The US Geological Survey's Mineral Commodity Summaries 2025 and the European Commission's Critical Raw Materials Factsheets both document that materials such as lithium, cobalt, nickel, and graphite have identified resources distributed across multiple continents. What constrains extraction is less frequently geology and more often permitting timelines, land access, environmental assessment, and community acceptance. These are substantial challenges, and they deserve the attention they receive. But they are not, in themselves, the reason that non-Chinese actors struggle to secure access to critical materials.

Processing and refining are where the picture changes. For rare earth elements, China accounts for over 85% of global processing capacity. For lithium, Chinese refiners produce approximately 60% of the lithium compounds used in battery manufacturing, despite China accounting for a smaller share of upstream mining. For cobalt, the Democratic Republic of the Congo produces the majority of global mine supply, but Chinese refiners convert over 70% of that mine output into the battery-grade chemicals that industrial buyers actually need. The same pattern, in varying degrees, applies across graphite, gallium, germanium, tungsten, and a number of other materials designated as critical on both sides of the Atlantic.

This concentration is not a geological accident. It is the cumulative result of decades of industrial policy, sustained public investment, tolerance for environmental externalities that were not priced into production costs, and a deliberate strategy of vertical integration into downstream manufacturing. By the time critical raw materials entered the strategic vocabulary of Western capitals in the late 2010s, China had already built the midstream infrastructure that the West is now attempting to rebuild.

The vicious circle

The European Court of Auditors used a sharp phrase in its Special Report 04/2026: the EU may be trapped in a vicious circle, where a lack of supply hinders the development of processing projects, which in turn reduces the impetus to secure supply. The same logic can be observed more generally. Building mines without corresponding processing capacity does not deliver resilience. It delivers a longer, more geographically distributed, dependency path.

Ore extracted in Europe, Canada, or Australia that must still be sent to Chinese refiners to become usable is not strategically autonomous output; it is raw material feeding the same dependency from a more diversified upstream base.

The implications of this logic have begun to manifest in European industrial decisions. Belgium's Solvay opened a rare earth processing facility in France in April 2025 and then earmarked significant volumes of output to US magnet manufacturers rather than European ones, citing stronger commercial commitment from US counterparts. US Rare Earth acquired the UK-based processor Less Common Metals in parallel. These are not isolated transactions. They reflect the structural logic of a US industrial policy designed to absorb available non-Chinese midstream capacity as rapidly as possible, and they illustrate that Europe's own hard-won processing investments can be drawn away from European supply chains by offtake arrangements that European buyers are not currently in a position to match.

This is worth underlining. It is possible for a jurisdiction to expand processing capacity on its own soil and still lose access to the output of that capacity. The midstream is where commercial and strategic leverage meet, and whoever offers the most credible combination of price, volume, and long-term commitment secures the material. Mining alone, without a commensurate ability to anchor downstream demand, does not change the outcome.

The pipeline problem

Even where processing is not the immediate constraint, the upstream picture is weaker than the headline investment figures suggest. The International Energy Agency's Global Critical Minerals Outlook 2025 reported that exploration spending plateaued in 2024, with overall investment in critical mineral development rising by just 5%, down from 14% in 2023. Adjusted for cost inflation, real investment growth was approximately 2%. Exploration continued to rise for lithium, uranium, and copper, but declined for nickel, cobalt, and zinc. Start-up funding is also slowing, and projects involving new entrants have been most affected by depressed mineral prices and market uncertainty.

The significance of these figures is temporal rather than immediate. Projects typically require 10 to 15 years to move from discovery to production. The European Court of Auditors noted that EU mining projects can take up to 20 years to become operational, particularly in jurisdictions where permitting processes are complex and land access is contested. Exploration spending that slowed in 2024 translates into a narrower project pipeline available in the mid-2030s. By the time that pipeline matters, the decisions that would have improved it will be a decade old and beyond correction.

This is one of the least well-understood features of critical raw materials supply. Unlike markets that can respond to price signals within a production cycle, CRM supply is structurally inelastic.

Price spikes cannot summon new mines into existence within the timeframe of a typical commodity cycle. Public investment in exploration today is not about solving the current supply question. It is about ensuring that the supply question a decade from now has any candidate answers at all.

Manufacturing's gravitational pull

Further downstream, manufacturing exerts a gravitational pull on the rest of the value chain that policy design has not yet come to terms with. Where manufacturing capacity locates, processing and refining tend to follow, driven by logistics costs, quality coordination, and the commercial logic of supplier proximity. Battery manufacturing illustrates the dynamic. The majority of global lithium-ion cell production takes place in Asia, primarily in China, South Korea, and Japan, and the processing and refining of battery-grade lithium compounds, cobalt chemicals, and graphite has concentrated around those manufacturing centres.

For jurisdictions seeking to diversify upstream supply, this creates a difficult coordination problem. Investment in new mines or new processing facilities is more likely to succeed commercially when paired with credible downstream demand in the same jurisdiction. But building that downstream demand requires simultaneous investment in manufacturing capacity, industrial ecosystems, and workforce skills, none of which can be conjured quickly. The EU's Net-Zero Industry Act and the US Inflation Reduction Act both attempt to address this through demand-side incentives, but the scale required to counteract decades of accumulated manufacturing concentration is substantial and the timelines are long.

The practical consequence is that narrowly focused upstream investment without a matching downstream strategy tends to produce orphan capacity: mines and processing facilities that exist but cannot find local markets and end up either closing or routing output back into the supply chains the investment was supposed to diversify.

Recycling, and the limits of the circular answer

Recycling is frequently invoked as a structural response to these dynamics, and its potential is real over a long enough horizon. But the near-term picture is more constrained than the rhetoric suggests. The European Court of Auditors found that of 26 materials it identified as critical for the energy transition, seven have end-of-life recycling rates between 1% and 5%, and ten, including lithium, gallium, and silicon metal, are not recycled at all. The reasons are not primarily technological. They relate to product lifetimes, with materials used in long-lived products not yet reaching end-of-life in meaningful volumes, collection infrastructure, and the unfavourable economics of recovering materials that are present in small quantities within complex assemblies.

The US presents a related inefficiency. The Payne Institute highlighted that approximately 880,000 metric tonnes of copper scrap were exported from the US in 2023, with around 40% going to China, even as the US imported refined copper. Here the constraint is neither technology nor product lifetime but the absence of domestic secondary processing capacity capable of absorbing available scrap at competitive cost. Recycling as a contribution to supply security requires the same midstream infrastructure that primary supply chains require. Without it, material flows back into the very supply chains that recycling is supposed to reduce dependence on.

From stages to systems

Viewed across its six stages, the critical raw materials value chain is not a chain at all in the conventional sense. It is a system whose most consequential vulnerabilities emerge from the interactions between stages rather than from the weaknesses of any single stage in isolation. A jurisdiction can invest heavily in mining and still depend on Chinese processing. It can build processing capacity and see the output flow to US rather than European buyers. It can accelerate manufacturing investment and find that upstream supply relationships pull toward the same regions that dominate processing. And it can invest in recycling only to watch scrap exports leave the jurisdiction because domestic secondary capacity does not exist.

These dynamics are what distinguish a functioning supply security strategy from an accumulation of individual investments. Strategic resilience is built by understanding where, across the value chain, the interactions between stages either reinforce or undermine the policy intent of any individual intervention. Mining matters. It is not where the chokepoint lies.

The next article in this series examines the policy and regulatory frameworks through which the EU and the US are attempting, with very different instruments and at very different scales, to address these structural dynamics.
