Europe’s approach to securing critical raw materials is undergoing a significant shift, moving away from traditional mining projects towards by-product recovery within existing industrial frameworks. This transition is largely a response to the pressing economic realities of high capital costs, lengthy permitting processes, and energy expenses. Rather than investing in new mines, which often face structural barriers, European stakeholders are increasingly focusing on upgrading existing metallurgical and chemical facilities to enhance their capacity for recovering critical materials.
The Challenges of New Mining Projects
New mining initiatives in Europe encounter substantial hurdles that cannot be easily mitigated by policy changes. The permitting process for new mines can take six to ten years, compounded by appeals and litigation risks. Furthermore, the capital intensity required for these projects is notably high, with costs often exceeding €70,000–100,000 per annual tonne of capacity. This financial burden is exacerbated by elevated electricity prices relative to global standards and increasing carbon costs under the EU Emissions Trading System, which can reach €90 per tonne of CO₂. These factors create a challenging investment environment, particularly for projects aligned with the Critical Raw Materials Act.
In contrast, by-product recovery projects present a more favorable risk profile. They utilize existing industrial assets, thereby avoiding land-use conflicts and the need for new tailings facilities. This method allows for quicker execution timelines—typically within 24 to 48 months—compared to the decades required for new mining operations.
The Metlen Gallium Project: A Case Study
A prime example of this evolving strategy is the €90 million financing from the European Investment Bank (EIB) for the Metlen Energy & Metals project at the Aluminium of Greece complex. This initiative focuses on enhancing bauxite refining and gallium recovery at an operational site, marking the first gallium production project funded by the EIB. Gallium is crucial for various high-tech applications but is not mined directly; it is recovered during bauxite refining processes.
By integrating gallium recovery into an existing refinery, the Metlen project achieves multiple strategic outcomes: it bolsters European supply security for a vital material while avoiding the environmental impacts associated with new mining operations. Additionally, it benefits from established energy management systems that mitigate electricity costs—an essential consideration given that energy represents a significant portion of operational expenses.
A Scalable Model Across Europe
The Metlen project exemplifies a broader trend across Europe’s mining landscape. In Finland, investments in cobalt refining have facilitated battery-grade cobalt sulfate production without necessitating new mines. Similarly, Terrafame’s operations in Sotkamo have transformed nickel production into an integrated source of battery chemicals through hydrometallurgical processing rather than traditional extraction methods.
Belgium’s Umicore complex operates as a hub for recovering multiple metals from complex feedstocks, emphasizing processing control over ore ownership. In Spain, Atlantic Copper’s upgrades at its Huelva smelter reflect this same logic by expanding recovery capabilities within existing facilities. Across northern Europe’s zinc refining sector, targeted enhancements have enabled the recovery of indium and germanium without new mining developments.
Policy Support for By-Product Recovery
From the perspective of financial institutions like the EIB and national development banks, projects focused on by-product recovery align better with policy objectives than traditional greenfield mining initiatives. The lower execution risk associated with existing operational assets reduces climate and biodiversity concerns since no new land disturbance is required. Moreover, these projects can deliver results before 2030, fitting neatly into political and industrial planning timelines.
This alignment has led to increased recognition of by-product recovery as strategic infrastructure eligible for long-term public financing. It enables Europe to leverage its legacy industrial base into a critical raw materials platform at a fraction of the cost and risk associated with developing new mines.
Implications for the Critical Raw Materials Act
The Critical Raw Materials Act emphasizes targets for extraction and processing; however, by-product recovery plays a crucial role in enhancing Europe’s processing capabilities where it currently lags behind global competitors. Prioritizing this model addresses Europe’s most pressing vulnerabilities in supply chains.
Policy implications include favoring strategic designations for by-product recovery projects at existing sites and ensuring that state aid frameworks support incremental upgrades over greenfield investments. Accelerating permitting processes should focus on modifications to current operations rather than expanding land use.
A Strategic Shift Already in Motion
Europe’s challenge in securing critical raw materials will not be resolved solely through mining or recycling efforts in this decade; it will require leveraging existing industrial assets effectively. By-product recovery stands out as a solution that consistently delivers speed and reliability under current economic conditions.
The EIB’s investment in gallium recovery at Metlen signifies a broader commitment to this strategy across various metals essential for modern technology. The key question now is how quickly this model can be expanded across Europe’s industrial base to ensure strategic supply security before opportunities diminish.
