International audience ; Rare earth elements, key to many high-technology applications, are regularly making headlines, even in general public newspapers. Will the word run short of rare earth elements and of the many applications that rest on their use? In support to French and European Union policy making, as well as in support to industrial clients, BRGM is monitoring rare earth markets from the supply and the demand sides, as well as for technological shifts that drive them. Not every rare earth element is effectively rare and there are well over 400 ongoing rare earth exploration projects worldwide. Nevertheless, some rare earth elements such as dysprosium, europium and terbium are rare, in high and fast growing demand; as they either are indispensable to the production of Fe-B-Nd (Dy) permanent magnets, the highest performance magnetic material currently being available at industrial scale, or to the production of phosphors essential to the production of fluorescent compact, energy saving, light bulbs and video displays. At the current 10% compound annual growth rate of the demand for these elements, the question arises of their the future availability. Among the many rare-earth bearing minerals apatite is of particular interest as a potential source of rare earth elements, as it is a widespread mineral, forming huge deposits such as the sedimentary and magmatic phosphate deposits. An overview of the potential of sedimentary phosphate deposits as an important source for future rare earth production is presented and discussed. In addition to knowledge about the distribution and concentration of individual rare earth elements in sedimentary phosphate deposits, it is also necessary to understand the partitioning of the individual elements between phosphogypsum and phosphoric acid in the fertilizer production process, as well as available technologies to recover and separate individual rare earth elements from these materials. This could pave the way to the generation of extra added-value for phosphate ...

L'industrie minérale doit prendre en compte de nombreux facteurs de risques : politiques, institutionnels, économiques, techniques, et sociétaux. Ces risques, amplifiés notamment par l'émergence de la Chine en tant qu'acteur de premier rang de l'industrie minérale mondiale, fragilisent les entreprises de l'Union européenne. C'est pourquoi, en réaction à cette situation dégradée, la Commission européenne a lancé l'Initiative Matières Premières et divers États membres, dont la France, développent des stratégies visant à sécuriser l'approvisionnement des entreprises.

ERECON (2014) Strengthening the European rare earths supply chain: Challengesand policy options. Kooroshy, J., G. Tiess, A. Tukker, and A. Walton (eds.). ; Policy recommendations:1.Maintaining and strengthening the European Rare Earth Elements (REE) skills and knowledge base through research funding, science and technology education and international cooperation.Without cutting-edge research and technical expertise, a European high-tech REE industry cannot flourish. The EC and Member States should support funding for research grants, scholarships, and training networks, and enhance European and international cooperation through coordinated calls, researcher exchanges, and joint high-level conferences.2.Creating the basis for informed decision-making on REEs through a European Critical Materials Observatory.Mapping and monitoring of REE supply chains is necessary for informed decision-making. Expertise in Europe could be pooled in a virtual Critical Materials Observatory that provides the public with consistent and authoritative knowledge on REEs (e.g., information on advanced exploration projects, prices, key demand and supply trends, and the urban mine potential).3.Support promising technologies through funding industry-led pilot plants for innovative HREE processing.The EC, industry and Member States should accelerate the commercialization and scaling up of key technologies through co-financing industry-led pilot plants. This should include pilots for REE recovery from heavy rare earths-rich minerals, direct-alloy recycling routes, process and sensor equipment for REE recycling, and REE recovery from industrial residues.4.Levelling the playing field for European HREE exploration through co-funding for prefeasibility and bankable feasibility studies.Support from federal and state governments in the U.S., Australia and Canada has played a critical role in advancing project exploration. The EC and Member States should evaluate possibilities for supporting the extensive R&D necessary for pre-feasibility and ...

The EC and Member States should evaluate possibilities for supporting the extensive R&D necessary for pre-feasibility and bankable feasibility studies, to avoid high quality deposits in Europe simply going unexplored.5.Making waste management REE-friendly through eco-design, incentive schemes for collecting priority waste products, and streamlining policy and waste regulation.The EC and Member States should promote recycling-friendly design to help identify and recover REE components in waste more easily. Potential incentives for stimulating REE waste collection should be evaluated and the shipment of REE wastes should be facilitated. More consistency should also be created in implementing and applying existing waste regulations.6.Boost supply security and de-risk strategic REE investment cases through enhanced cooperation among European end-users and other stakeholders.Leading end-users should engage in strategic cooperation across industry and with governments. This could include setting up a voluntary European 'critical raw materials fund', establishing a 'European Resource Alliance' similar to the German Rohstoffallianz, and convening a high-level taskforce to examine ways in which public funding could support resilient REE supply chains for Europe.
