Europe’s push to secure reliable supplies of critical raw materials is extending far beyond the development of new mines. Through its Horizon Europe research programme, the European Union is funding technologies designed to make mineral exploration, extraction, processing and recycling more efficient, less polluting and more transparent.
The strategy reflects a growing recognition that Europe cannot strengthen its raw-materials security simply by extracting more ore. The continent also needs technologies capable of reducing energy and water consumption, recovering valuable materials from waste, improving resource efficiency and providing greater visibility across supply chains.
Projects supported through Horizon Europe are exploring a wide range of solutions, including robotic drilling, artificial intelligence, digital twins, smart ore sorting, bioleaching, membrane separation, closed-loop water systems and recovery of metals from mining waste. The objective is to build a more resilient European minerals industry while reducing some of the environmental and social costs traditionally associated with mining and mineral processing.
Smart Technologies Aim to Make Mining More Selective
One of the major Horizon Europe initiatives is OPTIMINER, a project running from 2025 to 2028 with approximately €7.3 million in EU funding. The programme brings together several technologies intended to improve how valuable minerals are identified and recovered. Its work includes smart ore sorting, membrane-based hydrometallurgy, bioleaching, phytomining and digital modelling, with demonstration activities planned or conducted across Spain, Greece, Poland, Finland and Chile.
A central concept is to avoid treating every tonne of extracted material in the same way. Advanced sorting technologies can identify higher-value material at an earlier stage, potentially allowing lower-grade or uneconomic material to be rejected before it reaches energy-intensive crushing and chemical-processing stages. If successfully implemented at industrial scale, such systems could reduce energy demand, water consumption and waste generation while improving the efficiency of metal recovery.
OPTIMINER is also examining the broader environmental consequences of different processing routes. Its assessments consider factors such as energy use, water requirements, toxicity and waste. That life-cycle perspective is important because a technology that delivers higher metal recovery is not necessarily the most sustainable option if the improvement requires substantially greater energy consumption or chemical inputs.
Low-Emission Mining and Mine-Waste Recovery
Another major Horizon initiative, ROTATE, is focused on developing extraction and mine-waste technologies with the goal of achieving near-zero emissions and reducing pollution. The project has received approximately €11.4 million in EU funding and is scheduled to conclude in August 2026. Its work includes recovering secondary products from mining residues while seeking to improve the environmental and social performance of extraction activities.
The focus on waste is increasingly important as Europe searches for ways to increase domestic supplies without relying entirely on new mines. Mining residues can contain metals that were previously considered uneconomic to recover. Advances in processing technology can potentially turn some of those waste streams into secondary sources of critical raw materials. At the same time, old mining sites can present environmental hazards. Historical tailings may contain sulphides, heavy metals or unstable structures, meaning that reprocessing cannot be separated from remediation, monitoring and long-term waste management.
Turning Europe’s Mining Waste Into a Secondary Resource
Europe has thousands of active, inactive and historical mining-waste facilities. Many were developed during periods when metals that are now considered strategically important had little commercial value or could not be recovered efficiently using the technologies available at the time. The SCIMIN-CRM project is investigating whether these sites can become sources of critical raw materials.
The initiative has approximately €7.2 million in funding and includes case studies in Spain, Sweden, Austria and Bosnia and Herzegovina. Its approach combines resource assessment, recovery technologies and research into social acceptance. One potential advantage of recovering metals from existing waste is that it could reduce the need for new extraction while simultaneously addressing legacy environmental liabilities. The approach is not without risks. Old waste facilities may contain hazardous materials or have structural weaknesses. Any attempt to recover valuable metals therefore needs to be combined with rigorous environmental controls and long-term site management.
SCIMIN-CRM is also seeking to reduce the time needed to determine whether a mining-waste facility contains enough recoverable material to justify commercial development. Faster and more accurate assessment could help investors and operators identify promising secondary resources without committing large amounts of capital to unsuitable sites.
Robotics and Artificial Intelligence Enter Mineral Exploration
Digitalisation is another major theme in Europe’s mining research agenda. The PERSEPHONE project, supported by approximately €5 million, is developing autonomous technologies for near-mine exploration and the investigation of deeper mineral deposits. One of its key tools is the use of digital twins, which can create virtual representations of underground environments. These models can allow researchers and operators to simulate geological conditions and operational decisions before carrying out activities underground.
The technology could eventually help companies reduce uncertainty and improve the safety and efficiency of exploration and mining operations. Another initiative, MINOTAUR, is receiving close to €5 million to develop miniaturised robotic drilling systems combined with artificial-intelligence technologies. Smaller, more targeted drilling equipment could reduce the physical footprint of exploration campaigns while generating more detailed geological information.
For Europe, that could be particularly useful in regions where large-scale exploration activities face environmental or community constraints. Digitalisation should not automatically be equated with sustainability. Artificial intelligence, robotics and digital modelling only deliver environmental benefits if they result in measurable reductions in drilling, energy use, waste, land disturbance or worker exposure. The long-term value of these projects will therefore depend on demonstrating practical improvements rather than simply introducing new digital tools.
Building a European Lithium Processing Chain
Europe is also directing research toward lithium processing, an area central to the expansion of battery manufacturing. The LITHOS project is focused on producing battery-grade lithium hydroxide from European resources and related feedstocks. Its work covers processing routes associated with Finland, Portugal and France and has received approximately €7.1 million in EU support.
Among its priorities are closed-loop water systems and lower-carbon processing technologies. The broader objective is to reduce the environmental footprint of supply chains in which European manufacturers import raw materials that may pass through multiple countries for concentration, refining and chemical conversion before reaching European factories. Developing more processing capacity closer to European battery production could reduce supply-chain complexity while increasing the amount of economic value retained within Europe. It could also strengthen supply security for a material that is essential to many modern battery technologies.
Rare Earths: From Deposits to Magnets
The European strategy also extends to rare-earth elements. The SUPREEMO project is developing a European rare-earth value chain using material linked to Norway’s Fen deposit as well as residues generated through uranium processing in the Czech Republic. The project has approximately €6.4 million in funding and includes research into rare-earth separation, production of rare-earth oxides and demonstration-scale manufacturing of permanent magnets.
Its scope is significant because producing a rare-earth concentrate is only one stage of the supply chain. Europe also needs capabilities for separation, metal production, alloying and magnet manufacturing if it wants to reduce its dependence on overseas processing. The inclusion of permanent-magnet production therefore points toward a more integrated model in which mineral resources are connected directly to high-value industrial applications. That type of integration could be crucial for sectors such as electric vehicles, wind power, robotics, electronics and defence.
Recycling and Traceability Become Strategic Priorities
Horizon Europe is also addressing the circular economy and governance challenges surrounding critical minerals. The BATRAW project, completed in April 2026, received approximately €9.8 million to develop technologies and systems for battery-pack dismantling, sorting, recycling and traceability. The initiative focused on materials including lithium, cobalt, nickel, manganese, graphite, aluminium and copper.
Efficient recovery of these materials could provide Europe with an additional source of supply while reducing the quantity of battery waste requiring disposal. Recycling also offers an opportunity to reduce pressure on primary mining, although the economics and environmental performance of recycling depend heavily on collection systems, battery chemistry, processing efficiency and the value of the recovered materials.
Another Horizon project, MaDiTraCe, concluded in June 2026 after receiving approximately €11 million in EU support. The project explored digital, geochemical and artificial-material fingerprints designed to strengthen mineral certification and traceability from the mine through to finished products, including recycled inputs. Such technologies could help companies verify the origins of materials and provide stronger evidence for responsible-sourcing and environmental claims. But digital traceability alone cannot guarantee that a supply chain is sustainable. Reliable systems ultimately require independent verification, physical testing and credible data throughout the production chain.
Europe Prepares the Next Wave of Raw-Materials Research
The EU is continuing to direct funding toward technologies that could strengthen its critical-minerals supply chain. The 2026 Horizon Europe calls for raw materials covered areas including exploration, primary extraction, secondary resources and recycling, with combined published funding of approximately €69.5 million. A further opportunity is expected to open on 22 September 2026, when the 2027 Horizon topic for innovative raw-materials processing is scheduled to launch.
That programme has an indicative budget of approximately €49 million, with around four projects expected to receive between €10 million and €12.5 million each. The size and structure of these grants demonstrate a shift in European research policy. The focus is increasingly moving beyond laboratory experiments toward pilot projects and demonstration facilities capable of showing how technologies could operate under realistic industrial conditions.
The Real Test Comes After Research Funding Ends
Europe has no shortage of promising technologies for improving the way critical minerals are explored, extracted, processed and recycled. The harder challenge is commercialisation. A successful research project does not automatically become a profitable industrial operation. Technologies still need customers, permits, reliable raw-material supplies, competitive operating costs and sufficient long-term financing. For investors, the transition from demonstration plant to continuous commercial production is often the most difficult stage.
That means Europe’s success will ultimately depend on whether Horizon-funded technologies can move beyond research programmes and become part of functioning supply chains. If they can, innovations such as smart ore sorting, autonomous exploration, low-carbon lithium processing, rare-earth separation, mine-waste recovery, battery recycling and digital traceability could help reshape the European mining industry. The strategic goal is therefore larger than discovering new deposits. Europe is attempting to create a mining and processing system that uses fewer resources, produces less waste, recovers more valuable material and provides greater visibility over where raw materials come from and how they are processed.
The next decade will show whether that research investment can translate into commercially competitive mines, refineries and recycling facilities. For Europe’s critical-minerals strategy, the decisive step will be turning promising technology into industrial capacity that operates at scale.
