    Betolar–EcoGraf–GTK Epanko tailings trial: design and risk notes for mine planners

    Betolar–EcoGraf–GTK Epanko tailings trial: design and risk notes for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Betolar has entered a strategic collaboration with EcoGraf and the Geological Survey of Finland (GTK) at the Epanko graphite project in Tanzania to test whether mine tailings can be reprocessed using Betolar’s metal extraction technology. The process is designed to enhance metal recovery from graphite tailings while generating secondary raw materials suitable for low-clinker binders and other construction products. For mine planners and tailings engineers, this signals potential shifts in tailings characterisation, storage design and long-term geochemical behaviour if waste streams are repurposed as feedstock.

    Technical Brief

    • Collaboration centres on Epanko graphite project tailings in Tanzania, involving Betolar, EcoGraf and GTK.
    • GTK’s role likely includes mineralogical, geochemical and leaching characterisation of Epanko tailings streams.
    • Betolar’s process targets residual metals in graphite-processing tailings, implying chemical or hydrometallurgical extraction stages.
    • Secondary raw materials are intended for low-clinker binders, suggesting pozzolanic or alkali-activated tailings products.
    • Integration with EcoGraf’s flowsheet will require tailings handling modifications to separate suitable fractions for reprocessing.
    • Geochemical alteration of tailings via extraction may change long-term drainage chemistry and cover design assumptions.
    • Construction-product reuse would demand compliance with leachability and strength standards for cementitious materials.
    • Similar graphite projects could reassess tailings as potential binder feedstock, influencing future mining waste strategies.

    Our Take

    Graphite appears alongside lithium, nickel and rare earths in our database’s critical minerals coverage, and the related Verisk Maplecroft piece (12 Feb 2026) underscores that projects like Epanko in Tanzania will be benchmarked against South American assets on both stability and ESG performance.

    For EcoGraf, which is Australia-based but advancing the Epanko graphite project in Tanzania, demonstrating innovative tailings reuse with partners such as GTK and Betolar could materially strengthen its social licence and permitting narrative relative to other African graphite hopefuls in our coverage.

    Within the 1930 tag-matched pieces on projects and sustainability, there are only a handful where tailings are treated as a potential product stream rather than a waste liability, so any successful tailings valorisation at Epanko mine would place the project at the leading edge of graphite-sector waste management practice.

    Global battery demand and Australian lithium: processing shift for mine engineers

    Surging global demand for lithium-ion batteries for electric vehicles and grid storage is pushing Australia to move beyond spodumene concentrate exports into domestic refining and cathode‑grade chemical production. Industry proposals centre on converting hard‑rock feed into battery‑grade lithium hydroxide and carbonate in Western Australia, leveraging existing Tier‑1 deposits and port infrastructure but facing high energy costs, skills shortages and permitting timelines. For miners and process engineers, the shift implies greater focus on impurity control, reagent optimisation and integration of hydrometallurgical circuits with upstream mine planning.

    Bengalla growth for New Hope: strip mine sequencing and design notes for planners

    New Hope Group has lifted coal output across its Australian assets and is advancing growth plans at the Bengalla thermal coal mine in the Hunter Valley, where it holds an 80 per cent interest alongside Mitsui, Taipower and J-Power. The open-cut operation, which typically produces export-quality thermal coal for Asian power utilities via the Port of Newcastle, is the company’s key near-term expansion focus. For mine planners and geotechs, any Bengalla growth path will centre on additional strip mining, dragline and truck–shovel sequencing, and associated waste dump and haul road reconfiguration.

    Mining smarter with AI and data: edge network design notes for engineers

    Australian miners are hitting a data wall as high‑bandwidth sensors, autonomous fleets and video streams overwhelm traditional cloud links, pushing operations towards private LTE networks and on‑site edge computing. Vendors such as Vocus are pairing Starlink Business Rural satellite backhaul with 4G/5G private LTE to keep haul trucks, crushers and fixed plant connected in real time, even on remote pits and waste dumps. For engineers, this shift means designing networks and control systems around low‑latency, on‑site processing for fleet dispatch, collision avoidance and condition monitoring rather than centralised data centres.
