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.
