Critical Minerals Overview
Policy and Strategic Importance

"Criticality" is a cross-function of "supply vulnerability" and "economic importance." It is a policy variable, not a geological constant. Japan lists fluorine and boron as critical minerals. The United States does not. This maps the difference in semiconductor industrial depth between the two countries. In 2018 the US list had 35 minerals. By 2022 it expanded to 50. Each expansion was driven by industry lobbying and the rising political volume of emerging technology pathways.

High-purity quartz sand is still not on the US critical minerals list. Global high-end supply of this mineral is highly concentrated in two mines in Spruce Pine, North Carolina. It is an irreplaceable raw material for semiconductor and optical fiber manufacturing. When Hurricane Helene devastated the region in 2024, the global semiconductor supply chain briefly seized up. A mineral not on the list has more extreme supply concentration than most minerals that are on the list. The list-building framework overweights the "import dependence" metric and lacks the capacity to identify risk scenarios where domestic supply does not depend on imports but global output is highly concentrated in a small number of domestic nodes. This is not an oversight. It is a structural defect in institutional design.

Australia, Chile, and Argentina control roughly 80% of global lithium mining output. China holds over 65% of global lithium chemical refining capacity. The DRC supplies about 70% of the world's cobalt ore. Refining is likewise concentrated in China. The bottleneck is in midstream processing, not upstream mining. This point has been repeated too many times already and needs to be pushed one layer deeper into the refining segment itself.

China's technical accumulation in rare earth separation began with Professor Xu Guangxian's countercurrent cascade extraction theory in the 1960s and 1970s, followed by half a century of industry-academia iteration. Three to five years of subsidies cannot replicate this. Heavy rare earth (dysprosium, terbium) separation and purification processes are an order of magnitude more difficult than light rare earth processing. Over 90% of global heavy rare earth separation capacity is concentrated in ionic rare earth ore smelters in southern China. Discussing "rare earth self-sufficiency" without distinguishing between light and heavy rare earths lacks analytical precision.

Then there is the by-product issue. Gallium is a by-product of aluminum smelting. Germanium is a by-product of zinc smelting. Tellurium is a by-product of copper smelting. Indium is a by-product of zinc smelting. These minerals have no such thing as an "independent mine." It is not possible to decide to "open one more gallium mine" to increase supply. The only option is to increase aluminum smelting volume and then recover more gallium from the process stream. Supply is pinned by the market demand for an entirely unrelated metal. "Invest more in mining" is useless for by-product minerals. The lethal force of China's 2023 gallium and germanium export controls roots in exactly this: other countries cannot quickly build independent alternative supply because independent supply as an option does not physically exist. Increasing gallium output means increasing aluminum smelting, and global aluminum smelting itself is concentrating toward China. Increasing aluminum output means increasing electricity consumption. Aluminum smelting is an extremely power-intensive industry. Electricity cost determines smelter location. China's coal-power cost advantage and the Middle East's natural gas cost advantage mean these regions' share of aluminum smelting will continue to rise. Gallium supply concentration is not being broken. It is being further reinforced. Germanium is slightly different. Teck Resources' Trail smelter in Canada is one of the few germanium recovery sources outside China, but its output is small relative to global demand.

A conventional car needs about 20 kilograms of copper. A battery electric vehicle needs about 80. An onshore wind turbine needs about 500 kilograms of rare earth permanent magnet material. Global photovoltaic installation expansion is driving exponential demand growth for silver, tellurium, indium, and gallium. These demands are locked in by carbon neutrality targets written into law, with timeline rigidity. Even if a critical mineral's price triples, demand will not contract significantly, because a policy commitment like "ban sales of internal combustion vehicles by 2035" will not be withdrawn due to mineral price fluctuations. The economic term is low demand price elasticity.

Carbon neutrality targets lock in the functional demand for "decarbonization," not the specific mineral "lithium." If lithium iron phosphate (LFP) replaces ternary materials (NCM/NCA) faster than expected, the demand growth curves for cobalt and nickel will flatten. If sodium-ion batteries penetrate the energy storage sector at scale, lithium demand growth will also be clipped. The demand rigidity of most critical minerals is conditional, dependent on the direction of technology pathway evolution.

Demand rigidity is changing the valuation logic of mining investment. Traditional mining investment follows commodity price cycles. Prices high, financing easy. Prices low, projects stranded. Once the demand side is locked in by legislation, investors begin evaluating projects by long-term offtake agreements rather than spot prices. Critical mineral investment is shifting from a cyclical industry toward a logic resembling infrastructure investment. Returns are not explosive. Duration is long. Certainty is high. This valuation paradigm shift has not yet been fully digested by mainstream mining investors.

Buyers are locked in by policy commitments on purchase volumes. Sellers naturally raise the price. This is the underlying economic logic behind resource nations' strengthening of export controls.

Indonesia banned nickel ore exports in 2020, requiring foreign companies to build smelters domestically. Zimbabwe banned unprocessed lithium ore exports. Chile requires the state to hold majority equity in lithium projects with technology transfer clauses. The DRC is renegotiating profit-sharing agreements with international mining companies. The core strategy is trading mineral rights for industrial chains.

After Indonesia's ore ban, massive capital flowed in to build nickel smelters and battery nickel intermediate product capacity. Indonesia went from a pure ore exporter to one of the world's major refined nickel and ferronickel producers in under five years.

Most of the smelting capacity that flowed in was invested and operated by Chinese companies. The intellectual property of the core smelting technology (HPAL, high-pressure acid leaching) was not transferred to Indonesian domestic entities. Indonesia gained employment and tax revenue. On the technology level it still depends on foreign operators. The overwhelming majority of products flow back into the Chinese battery supply chain. Indonesia did not build its own battery manufacturing capability as a result. This resembles what many developing countries experienced in the last century: foreign capital brought factories, took away profits and technology control, and left behind jobs and environmental burdens. The environmental impact of nickel smelting in Indonesia has already triggered sustained protests from local communities, especially around tailings management from the HPAL process. The Indonesian government is walking a tightrope between expanding smelting capacity and responding to environmental and social pressure. Namibia and Zimbabwe should look at the problems Indonesia is now facing before copying its model.

When the direction of China-Australia relations and US-Australia relations align, friendshoring runs smoothly. The moment a directional divergence appears (for instance when Australia's trade interests with China conflict with America's containment strategy), the "friend" shore becomes a multilateral bargaining node requiring difficult balancing. Alliance relationships in the minerals domain are not something you can simply transpose from a security alliance like NATO. Security alliances have a common threat as binding agent. Upstream-downstream relationships in mineral supply chains are fundamentally buyer-seller interest negotiations.

Oil strategic reserves work because oil is highly standardized, storage technology is mature, and release mechanisms have established market interfaces. Critical minerals are different. Battery-grade lithium carbonate and industrial-grade lithium carbonate are not interchangeable. The storage ratios of different rare earth elements must precisely match downstream formulation requirements. Some chemicals and precursors have defined shelf lives. If sodium-ion batteries reach scale commercialization within five years, lithium compounds stockpiled today face strategic depreciation. These three problems are frequently discussed.

There is almost no transparent data globally on the actual scale of national critical mineral reserves. China's State Reserve Bureau never publicly discloses stockpile volumes for rare earths and other strategic materials. Japan's JOGMEC maintains rare metal reserves with extremely limited public information on specific categories and quantities. In oil markets, IEA member states are obligated to publicly disclose strategic petroleum reserve levels, and the market can price buffer capacity. In critical minerals, no international mechanism requires reserve transparency.

The US could try to push for a critical minerals reserve transparency mechanism, similar to the IEA's requirements for oil reserves. The problem is China would almost certainly not join such a mechanism, because the opacity of reserves is itself a strategic asset. Publishing your reserve data allows your adversary to precisely calculate your endurance limit, and calibrate control policies to exactly the point where you cannot hold out. Maintaining ambiguity is the rational choice. So this information black box will likely persist for a long time.

Japan's approach has reference value: physical reserves plus technology hedging. Its rare earth strategy simultaneously advanced permanent magnet technology that reduces heavy rare earth usage (grain boundary diffusion technology) and rare-earth-free motor designs. Reserves and technology hedging work in tandem. Betting everything on reserves means using a static tool against a dynamic threat.

Global lithium recycling rate is below 5%. Cobalt recycling rate is slightly higher, concentrated mostly in small batteries from consumer electronics. The large-scale wave of retired EV battery recycling will not arrive until after 2030. Rare earth recycling rate is below 1% due to extreme dispersion in end products and complex separation processes. When primary ore mining costs are lower than recycling costs (still the case for most critical minerals today), the market will not spontaneously build recycling systems.

In 2023 lithium carbonate crashed from 600,000 RMB per ton to below 100,000 RMB per ton, and large numbers of Chinese lithium recycling companies immediately fell into losses and shutdowns. If diversified supply successfully drives down mineral prices, the recycling economy's business model gets destroyed simultaneously.

This contradiction seems obvious once stated. But going through the critical minerals strategy documents of various countries, supply security and recycling economy appear as parallel objectives in the same document with no paragraph in between discussing the logical tension between them. Acknowledging this contradiction means having to make a choice: either accept that mineral prices remain at elevated levels to support the commercial viability of recycling (which amounts to imposing additional cost on downstream manufacturing), or accept that recycling contributes little in the short-to-medium term and concentrate resources on diversification and substitute materials. Documents that try to cover both ends read well. On implementation they serve neither end well.

Unless the policy design routes around mineral price volatility. Specifically, this means providing the recycling system with long-term, stable institutional subsidies or mandatory quotas that are not linked to mineral prices. The mandatory recycled-material content requirements in the EU's New Battery Regulation take this path: regardless of whether prices are high or low, batteries must contain a certain proportion of recycled materials, which creates a floor demand for recycling at the regulatory level that is immune to spot price fluctuations. The design logic is right. Effectiveness depends on execution.

2025 to 2035 is the steepest decade for global electrification and energy transition demand ramp-up. Recycling will contribute almost no meaningful incremental supply during this decade. The "30% recycling share by 2040" figures that appear in long-term forecasts should not be used to relieve the urgency of the present.

The polymetallic nodules of the Clarion-Clipperton Zone (CCZ) in the Pacific contain vast quantities of manganese, nickel, cobalt, and copper. The International Seabed Authority (ISA) has not approved any commercial mining permits to date. Uncertainty in environmental impact assessment, the risk of irreversible damage to deep-sea ecosystems, and immature extraction technology make this pathway unlikely to contribute meaningful supply within a decade. Direct lithium extraction (DLE) from geothermal brine, oilfield produced water, or even seawater is technically feasible in principle but has very few commercial-scale operating cases. Rare earth extraction from coal ash and acid mine drainage has received DOE funding for multiple projects, but output is orders of magnitude below global demand.

In the ISA's exploration permit allocation, China holds among the largest number of exploration contracts and the greatest area coverage of any country. Under the ISA's one-country-one-vote mechanism, China wields considerable influence in the ISA Council through its infrastructure investments and diplomatic relationships with Pacific island nations and African countries. Before anyone lifts the first polymetallic nodule from the seabed, the competition over rule-making authority and exploration block allocation is essentially complete. Latecomers will face a fait accompli. Resource competition always starts long before extraction begins. The history of coal and oil has repeatedly confirmed this.

China imposed export controls on gallium and germanium in 2023, subsequently adding graphite and antimony to the controlled list. The timing and category selection of each round of controls corresponds closely to the escalation cadence of semiconductor export controls. Critical minerals have become a calibratable weapon in geopolitical competition, capable of precisely adjusting pressure intensity. Not severe enough to trigger systemic decoupling, but sufficient to deliver targeted impact on specific industrial chains.

Some have drawn an analogy to Cold War nuclear deterrence, calling it "Mutually Assured Supply Disruption." The stability of nuclear deterrence depends on roughly symmetrical strike capabilities between both sides. The asymmetry in critical minerals is pronounced. China's advantage in mineral processing is broadband, covering rare earths, lithium, cobalt, gallium, germanium, graphite, antimony, and more than a dozen other categories. The advantage of the US and its allies in semiconductor manufacturing equipment and EDA design software is also extremely concentrated, but covers far fewer categories. Broadband versus narrowband. The strategic space is inherently unequal. China can selectively control different minerals to precisely hit different industries. Like someone with a dozen rounds of varying caliber facing someone with only two large-caliber shells. The shells pack more punch, but can only be fired twice, and each shot carries greater collateral damage.

Japan's response after the 2010 China-Japan rare earth incident provides a time reference. Sojitz Corporation over the following decade systematically invested in rare earth projects in Australia, Vietnam, and India. JOGMEC provided exploration funding and risk guarantees. The government provided infrastructure support for resource countries through ODA (Official Development Assistance). The three actors worked in concert to build a "national team model" supply diversification system, while simultaneously advancing permanent magnet technology breakthroughs to reduce heavy rare earth usage. By 2023, when China imposed export controls on rare earth processing technology, the impact on Japan was far smaller than thirteen years earlier. This response took a full ten years. Ten years. Election cycles run four to five years. Mineral security requires more than a decade of continuous investment. The strategic patience problem of democratic polities is exposed more fully in critical minerals than in perhaps any other domain.

The coercive value of mineral weapons depends on one premise: the speed of building alternative sources. If consuming nations can build smelting and processing capabilities not dependent on a single adversary within five to ten years, the weapon loses its power. The side with resource advantage needs to maximize leverage value within the window period. The consuming side needs to compress the window's duration. Both sides are racing against time, running on the same track, in opposite directions.

In the United States, the average time from discovery to production for a new mine is 7 to 10 years. Environmental review and permitting approval account for more than half of that. Canada and Australia are slightly shorter but still commonly exceed five years. A Chinese mine or smelter typically takes only two to three years from project initiation to production.

This permitting speed gap is one of the greatest structural disadvantages of the Western mineral supply chain. The question is not whether environmental standards should be lowered. They should not. The question is whether procedural redundancy in the environmental review process, duplicative multi-agency approvals, and judicial challenge mechanisms can be drastically simplified without lowering substantive environmental requirements. Declaring critical minerals a national security priority while refusing to reform the administrative approval system means all strategy documents and appropriations bills will eventually hit the same wall. The US Inflation Reduction Act of 2022 and the EU Critical Raw Materials Act of 2024 both contain provisions for accelerated permitting. Effectiveness on the ground remains to be seen.

The US-led Minerals Security Partnership (MSP) is signing memoranda of understanding far faster than smelters are breaking ground. This is the most prominent execution deficit in current multilateral mineral cooperation, and the most anxiety-inducing element. Memoranda of understanding cannot smelt ore.

On substitute materials. Lithium manganese iron phosphate (LMFP) partially replacing high-nickel ternary materials. Ferrite permanent magnets replacing rare earth permanent magnets in mid-to-low-end motors. Silicon carbide and gallium nitride replacing traditional silicon-based semiconductors to reduce per-unit device material consumption. Each pathway could reshape the demand structure of a given critical mineral category on a ten-year horizon. Each also needs to cross the "valley of death" between laboratory validation and commercial-scale production, that stretch where funding dries up and markets are absent. Government should be deploying resources in that stretch, not at the stage where technology is already mature and capital markets are already willing to enter.

The IEA for oil took the 1973 oil crisis to be born. The critical minerals domain is still in a pre-crisis window. This window is when building a multilateral coordination mechanism costs the least. A "Critical Minerals IEA" concept: a coordinating body composed of major consuming nations, with members bearing minimum reserve obligations, sharing market intelligence, and activating joint releases or joint procurement during supply crises. Once a large-scale supply disruption occurs, countries will act unilaterally in panic, rush-purchase, hoard, drive up prices, and deepen chaos. Cooperation mechanisms built in peacetime cost the least. Those built during crisis cost the most. The lesson of 1973 is clear.
