EXCEED
EXCEED’s meta-objective is to unleash the full CRM and industrial mineral potential of Europe’s vast Li LCT-pegmatite and Rare-Metal Granite hard-rock resources
EXCEED’s multi-metal/mineral, zero-waste mining-and-refining approach adopts a mineral-centric, integrated methodology via the application of a first-of-its-kind predictive and forensic geometallurgy, supported by enhanced in-line characterisation tools and the development of digital twins. Using four premier European pegmatite and RMG case studies, EXCEED develops, upscales & demonstrates cost-effective, sustainable and responsible extraction routes for recovering the CRMs and industrial minerals as by-products from Li-bearing hard-rock ores. A suite of CRMs will be extracted and refined, while diverse industrial minerals will be refined and valorised in low-carbon building materials.
Science/technology-related objectives:
- To recover by-product CRMs and industrial minerals during Li production from LCT-pegmatite and (low-grade) Rare-Metal Granite (RMG) hard-rock deposits through a mineral-centric, integrated approach based on increased orebody knowledge, the use of predictive & forensic geometallurgy and the development of online technologies to provide real-time mineralogical information for process optimisation
- To develop new, energy-, material- and cost-efficient flowsheets for recovering CRMs (Nb, Ta, W, Nd/Pr, Be), Sn and industrial minerals (quartz, feldspar, mica) as by-products from two LCT-pegmatite ores (Rapasaari/Syväjärvi, Keliber Oy; Mina do Barroso, Savannah), two Rare Metal Granite ores (St Austell, Beauvoir) and monazite tailings (St Austell’s kaolin operations)
- To valorise the mineral side-streams (quartz, feldspar, mica) from processing of LCT-pegmatite & RMG ores, as secondary raw materials in construction applications (alkali-activated & supplementary cements; ceramics; lightweight aggregates (LWA) for concrete), ensuring safety & environmental feasibility in line with standardisation practices
- To remove any PHEs (U/Th) and, subsequently, separate and refine the distinct (non-Li) critical metals (Ta, Nb, W, Nd/Pr, Be) and other valuable metals (Sn) that are present in the CRM-bearing concentrates obtained from mineral processing of LCT-pegmatite and RMG ores
- To integrate EXCEED’s innovative solutions into near-zero-waste, multi-metal/mineral mining and refining process concepts and to demonstrate them in pilots at TRL6–7, supported by the integration of the digital twins
- To make a novel, integrated Life-Cycle, Techno-Economic and Human Impact Assessment, which will incorporate Social License to Operate (SLO) principles for the newly developed, mineral-centric, integrated processing routes for LCT-pegmatites and RMGs
Other objectives:
- To develop a framework of best corporate practices to achieve a SLO, thereby improving the public awareness, acceptance and trust in next-generation, zero-waste mining and sustainable metallurgical processing in Europe
- To cluster EXCEED with projects from the HORIZON-CL4-2022-RESILIENCE-01-07 call, the previous HORIZON-CL5-D2-01-01 call and related calls from the Destination “Increased autonomy in key strategic value chains for resilient industry” as well as on-going H2020 projects on next-generation batteries (call H2020-BAT-2019) + contributing to Batteries Europe and the objectives of the European Raw Materials Alliance
- To communicate in a gender-balanced way the relevance of EXCEED and disseminate the project results to diverse audiences, while improving the public awareness, acceptance and trust with respect to next-generation, zero-waste mining and sustainable metallurgical processing of Li-pegmatite/RMG hard-rock deposits and mines in Europe
- To exploit the results of the project and increase the competitiveness of the Li-producing industry in Europe as well as create new business models for multi-metal (CRM/)/mineral mining of LCT-pegmatite and RMG/greisen deposits
- To develop an effective, transparent and comprehensive administrative, financial, legal, data, ethics and material-flow management to ensure the project’s successful outcome
EXCEED is a response to HORIZON-CL4-2022-RESILIENCE-01-07 Innovative solutions for efficient use & enhanced recovery of mineral & metal by-products from processing of raw materials.
