    UK scientists’ protein membranes for cleaner lithium: DLE implications for mine planners

    UK scientists’ protein membranes for cleaner lithium: DLE implications for mine planners

    First reported on MINING.com

    30 Second Briefing

    UK researchers led by the University of Birmingham have secured £6.2 million from the UK’s Advanced Research and Invention Agency to develop protein-based membranes that can selectively separate lithium from sodium for high-purity battery-grade compounds. The three-year project will engineer S‑layer proteins into large-area membranes with uniform, programmable pores, combining AI-guided protein design by Fold9, membrane scale-up and testing by Evove, and high-throughput variant screening by Adaptyv Bio. Success would provide lithium producers with a new DLE route, contingent on achieving industrial-scale durability and consistent separation performance outside the lab.

    Technical Brief

    • S-layer proteins are being re-engineered into 2D lattices forming uniformly sized ion-selective pores.
    • ARIA funding sits within its Universal Fabricators programme, focused on protein-based manufacturing building blocks.
    • Fold9 leads AI-guided protein sequence design to tune pore geometry and ion-binding behaviour.
    • Evove is responsible for membrane fabrication, scale-up and performance testing under realistic brine operating conditions.
    • Adaptyv Bio supplies high-throughput screening, enabling evaluation of thousands of protein variants for Li/Na selectivity.
    • Research methods integrate computational protein design, structural biology, experimental screening, protein production and membrane characterisation.

    Our Take

    The University of Birmingham already features in our database for campus-scale sustainability and life-science infrastructure work, which suggests this lithium and sodium separation research is being embedded in a broader institutional push on low-impact technologies rather than as a stand-alone lab initiative.

    Within the 96 keyword-matched lithium and sodium pieces in our coverage, most focus on brine or hard-rock extraction projects, so a UK-based biology-led route positions this work in a niche space that could appeal to European OEMs seeking lower-footprint, non-brine supply options.

    The £6.2-million ARIA-backed programme in the United Kingdom signals that early-stage bio-based battery-materials processing is starting to attract public innovation capital at a scale comparable to pilot mining projects, which may give UK start-ups like Fold9 and Evove leverage when negotiating future industrial or automotive partnerships.

    SigraFi’s $35m ASGM facility: supply chain and risk notes for gold project teams

    SigraFi has secured a $35 million credit facility from a consortium led by UAE-based Ronin Commercial Brokers to finance gold offtake from organised artisanal and small-scale gold mining cooperatives in the DRC, Zambia and South America. The company already works with PeaceGold in eastern DRC, covering 11 cooperatives and about 25,000 miners in Ituri Province, using multi-year contracts and guaranteed offtake at competitive prices. The model targets ASGM’s roughly 20% share of global newly mined gold by providing traceable, compliant supply to institutional refiners previously reliant on informal channels.

    Tahmoor Colliery sale: restart staging and ground control checks for engineers

    Completion of the Tahmoor Colliery sale in New South Wales to the GEAR/M Resources Consortium moves the underground coking coal mine closer to full restart, with about 150 workers already back on site undertaking initial mining activities. The new operator plans a staged ramp-up, progressively recalling additional personnel and recommissioning equipment to restore longwall production. Geotechnical and operational teams will be focused on revalidating ground control, ventilation and gas management systems after the shutdown period before returning to full output.

    Avonbank mineral sands mining licence: design and tailings notes for engineers

    WIM Resource has secured a mining licence for the Avonbank mineral sands project in western Victoria, located about 15km north-east of Horsham, to extract a heavy mineral assemblage including zircon, titanium minerals and rare earth elements. The approval follows a formal assessment by Resources Victoria, clearing the way for large-scale dredge or dry mining of strandline-style deposits typical of the Murray Basin. For geotechnical and processing teams, the mix of zircon and rare earth-bearing minerals signals complex separation flowsheets and tailings management in fine-grained sands.
