    Perpetua–INL minerals recovery pilot: flowsheet and design insights for mine engineers

    Perpetua–INL minerals recovery pilot: flowsheet and design insights for mine engineers

    First reported on International Mining – News

    30 Second Briefing

    Perpetua Resources has signed an agreement with Idaho National Laboratory, operated by Battelle Energy Alliance, to host, commission and run a flexible, modular pilot plant to recover critical and defence-related minerals, including antimony, from Perpetua’s orebodies. The pilot is expected to test flowsheets for selective antimony recovery alongside other strategic elements, using containerised process modules that can be reconfigured for different ore types and chemistries. Outcomes will inform full‑scale processing design for the Stibnite Gold Project and potential US domestic supply chains for military‑grade antimony products.

    Technical Brief

    • Agreement is structured via Battelle Energy Alliance LLC, INL’s managing and operating contractor.
    • INL will be responsible for hosting, commissioning and day-to-day operation of the pilot plant.
    • Scope explicitly targets “various” critical and defence-related minerals beyond antimony from Perpetua’s existing orebodies.

    Our Take

    Antimony appears only in several keyword-matched pieces in our database, so Perpetua Resources’ Idaho work with Idaho National Laboratory positions the US as a rarer North American case of upstream antimony capability compared with the more common gold, copper or lithium stories.

    Perpetua Resources also features in MINING.COM’s November Global Mining Power Rankings coverage, signalling that investors are already tracking its antimony exposure as part of a broader critical minerals narrative rather than as a niche by-product play.

    A US-based antimony recovery project in Idaho has strategic implications for defence supply chains, as most recent antimony coverage in our database still centres on foreign supply risk and processing bottlenecks rather than domestic R&D-led recovery routes.

    CITIC HIC semi-mobile crusher at Duobaoshan: design and throughput notes for mine planners

    A PSZ3000-B semi-mobile gyratory crushing station, independently designed and built by CITIC Heavy Industries in Luoyang, has completed no-load and load commissioning at Zijin Mining’s Phase II expansion of the Duobaoshan copper-molybdenum mine in Heilongjiang, with all performance indicators meeting design standards. The semi-mobile unit is configured as a primary crusher station for the expanded open pit, allowing truck-fed in-pit crushing with conveyor transfer to downstream processing. For mine planners and plant engineers, the successful commissioning confirms Chinese-built large semi-mobile gyratory technology as a viable option for high-throughput greenfield and brownfield expansions.

    LEEA GLAD procurement survey: compliance and lifecycle insights for mine teams

    LEEA has launched a procurement-focused survey to feed into a new white paper scheduled for release on Global Lifting Awareness Day (GLAD) on 2 July 2026, with details hosted on the updated campaign site globalliftingawarenessday.com. Targeted at stakeholders who specify or purchase cranes, hoists, slings and other lifting accessories, the initiative centres on the theme “Not all lifting equipment is…”, aiming to capture how compliance, whole‑life cost and inspection regimes are currently weighted in buying decisions. Mining owners, EPCMs and contractors can use the findings to benchmark procurement practices against industry expectations and tightening safety standards.

    Hitachi EH5000 100,000‑hour milestone at Lumwana: capex and fleet life notes for planners

    Three 296 t class Hitachi EH5000 rigid dump trucks at Barrick’s Lumwana copper mine in Zambia have each passed 100,000 operating hours, an unusually high lifecycle for ultra-class haulage equipment in hard-rock copper operations. The milestone, marked at a joint Barrick–Hitachi recognition ceremony, points to effective component rebuild strategies, condition-based maintenance and strong dealer support for the EH5000 fleet. For mine planners and maintenance teams, it signals potential to extend truck life beyond typical replacement cycles, with implications for capex timing and fleet renewal strategies.
