The global competition to secure critical minerals is entering a new and more complex stage. For much of the past decade, the strategic conversation focused largely on high-profile materials such as lithium, cobalt, and rare earth elements—resources essential for electric vehicles, renewable energy technologies, and modern electronics.
Today, however, policymakers and industry leaders are expanding their focus. A growing list of lesser-known metals is beginning to attract attention as governments recognize that the energy transition depends on far more than a handful of widely discussed resources.
One of the most striking examples is antimony, a metal that until recently remained largely outside public discussion but is now emerging as a significant strategic concern in global supply chains.
Why Antimony Suddenly Matters
Antimony is used in a surprising range of technologies. It plays an important role in flame-retardant materials, semiconductor components, military equipment, and specialized alloys. In the energy sector, it is also used in lead-acid batteries and is being explored in several next-generation battery chemistries.
Despite these diverse applications, global supply of antimony remains highly concentrated. According to analyses cited by the World Economic Forum, China, Russia, and Tajikistan together account for more than 90 percent of global antimony mine production. Such concentration creates significant risks for industries that rely on the metal.
These concerns intensified in August 2024, when China introduced export controls on antimony-related products and later tightened restrictions on shipments to the United States. The immediate market reaction was dramatic. Prices surged to nearly $50,000 per tonne, roughly ten times higher than the average price observed over the previous five years. The sudden spike illustrated how quickly an obscure commodity can become strategically important when supply chains tighten.
The Expanding Universe of Critical Minerals
The case of antimony reflects a broader shift in how governments view mineral supply chains. As the world moves toward electrification and low-carbon technologies, demand for a wide range of metals is rising rapidly.
Battery technologies require lithium, nickel, cobalt, and graphite. Wind turbines and electric vehicles rely on rare earth magnets. Modern power grids and renewable infrastructure depend heavily on copper.
According to projections from the International Energy Agency, global demand for critical minerals could triple by 2030 and quadruple by 2040 if countries remain on track toward net-zero emissions. Yet production and processing capacity for many of these materials remains concentrated in only a few countries. China alone dominates the refining stage for 19 of the 20 critical minerals examined by the IEA, highlighting the imbalance between rising demand and geographically limited processing capacity. This imbalance is now influencing industrial strategy across major economies, from North America to Europe and Asia.
Mining Is Only Part of the Story
Although public debates often focus on discovering new mineral deposits, the most strategic stage of the supply chain frequently lies elsewhere. For many critical minerals, the refining and chemical processing stage is where the majority of value is created. Raw ore or mineral concentrate must undergo complex metallurgical transformations before it becomes usable in batteries, magnets, semiconductors, or advanced industrial equipment.
Rare earth elements provide a clear example. After mining, the ore must be chemically separated into individual elements through solvent extraction circuits that may involve dozens of stages. These elements are then transformed into metals, alloys, and eventually high-performance magnets.
Lithium follows a similar pattern. Material extracted from hard-rock mines or brine deposits must be converted into battery-grade lithium hydroxide or lithium carbonate through sophisticated chemical processes.
Over the past three decades, much of this refining capacity migrated to regions offering lower energy costs, supportive industrial policies, and fewer regulatory barriers. China invested heavily in such infrastructure, gradually building the world’s largest processing ecosystem for rare earths, graphite, and many battery materials. As a result, minerals mined in countries across the globe are often shipped to China for processing before being exported again as refined products.
Antimony as a Case Study in Supply Risk
The sudden volatility in antimony markets demonstrates how vulnerable these concentrated supply chains can become.
Unlike widely discussed metals such as copper or lithium, antimony occupies a relatively small market. However, its importance in several strategic industries gives it outsized geopolitical significance. The metal is widely used in flame retardants, particularly in plastics and textiles that must meet strict fire-safety standards. It also appears in infrared detectors, semiconductor technologies, and specialized alloys used in defense applications.
Because production is so geographically concentrated, any disruption—whether political, economic, or regulatory—can quickly affect global supply.
When export restrictions tightened in 2024, governments and manufacturers suddenly realized how exposed they were to disruptions in a market that had previously received little attention.
The Rise of Mineral Security Policies
In response, governments around the world are adopting policies aimed at strengthening supply-chain security for strategic metals.
In the United States, the Department of Defense has begun supporting domestic production and refining capacity for several critical materials. One initiative included a $245 million offtake agreement designed to secure antimony supply, alongside funding to expand domestic processing infrastructure.
The European Union has launched a similar strategy through the Critical Raw Materials Act, which aims to reduce dependence on external suppliers by increasing domestic mining, refining, and recycling capacity. Under the legislation, the EU intends to ensure that 40 percent of critical minerals consumed in Europe are processed within the region by 2030.
Reaching that goal will require significant investment in smelters, chemical conversion plants, and advanced materials facilities across the continent.
Europe’s Midstream Industrial Opportunity
Europe is gradually beginning to rebuild parts of its mineral processing industry. New rare-earth processing projects are emerging in Estonia and France. Lithium conversion plants are being developed in Germany, Portugal, and Finland. Meanwhile, Nordic countries are expanding battery-metal refining capacity to support Europe’s growing electric-vehicle industry.
Together, these developments are slowly forming a continental network that connects mining projects, refining plants, and manufacturing facilities.
However, the scale of investment required remains enormous. Analysts increasingly estimate that more than €200 billion could be needed to develop the midstream infrastructure necessary for Europe’s electrified economy. The antimony supply shock provides an important reminder of why these investments matter. Securing raw materials alone is not enough; resilient refining capacity is equally critical.
Recycling and the Circular Economy
Another approach gaining momentum involves expanding the recycling of critical minerals.
Electric vehicles, wind turbines, batteries, and electronic devices contain substantial quantities of valuable metals. As these products reach the end of their lifecycle, recovering and reprocessing those materials could provide an important secondary supply source.
A circular-economy strategy could reduce dependence on primary mining while helping stabilize supply chains. By reclaiming metals from industrial waste and end-of-life equipment, countries can also reduce the geographic concentration of supply. Still, recycling alone cannot meet the rapidly growing demand for critical minerals. New mines and processing facilities will remain essential.
The Next Stage of the Minerals Race
The story of antimony highlights a broader reality: the list of strategic minerals is expanding. Materials that once attracted little attention can quickly become geopolitically significant when supply chains tighten or global demand shifts.
As the energy transition accelerates, governments and industries will increasingly need to track not only widely known resources like lithium, nickel, and copper, but also a growing range of specialized metals used in advanced technologies.
This shift reflects a deeper truth about the modern industrial economy. Technological progress depends on complex networks of materials, processing facilities, and global logistics systems. Electric vehicles, renewable energy systems, and digital infrastructure all rely on metals that must be mined, refined, and transformed through sophisticated industrial processes.
Securing those supply chains has therefore become one of the central challenges of the global energy transition. The race for critical minerals is no longer simply about discovering resources underground. It is increasingly about building the industrial ecosystems capable of turning those resources into the materials that power the modern world.
