    South32 Hermosa Jameson Concentrator choice: process design notes for engineers

    August 13, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    South32’s Hermosa zinc-manganese-silver project in Arizona has selected Glencore Technology’s Jameson Concentrator for its processing plant, leveraging the compact Jameson Cell-based flowsheet to cut footprint and energy use while supporting higher automation. The modular, small-footprint design is intended to simplify layout and maintenance in the underground-linked plant and reduce structural steel and concrete demand. For process engineers, the choice signals a push towards fine grinding and high-intensity flotation to maximise metal recovery while tightening water and tailings management.

    Technical Brief

    • Jameson Concentrator selection is tied to Hermosa’s “best-practice critical minerals” design brief in Arizona.
    • Glencore Technology positions the concentrator to support higher inherent process safety in plant layout.
    • Hermosa’s processing plant is being engineered explicitly for “increasingly automated” operation from first production.
    • South32 is targeting reduced environmental impact at Hermosa through flowsheet and equipment choices, not only power sourcing.

    Our Take

    Across our recent South32 items, Hermosa and the Sierra Gorda copper operation appear as the main base‑metals growth platforms, suggesting that deploying Jameson technology at Hermosa could become a reference flowsheet for other South32 critical‑minerals assets if it delivers the expected fine‑grind and recovery performance.

    Within the 112 critical‑minerals‑tagged pieces in our database, few US projects have both FAST‑41 status and a defined processing technology path, so Hermosa’s combination of streamlined permitting and early plant design choices may give it a schedule and cost‑of-capital advantage over other Arizona and wider US base‑metal developments.

    NioCorp Railveyor electrification at Elk Creek: design notes for mine planners

    NioCorp will deploy the Railveyor™ automated rail-based haulage system as the core ore movement and electric underground haulage solution in its Elk Creek critical minerals project in Nebraska, integrating it into a new twin-ramp orebody access layout detailed in its 2026 feasibility study. The Railveyor installation is intended to replace conventional diesel truck haulage over the main ramp profile, cutting ventilation demand and enabling a fully electrified materials handling chain from stopes to surface. For mine planners and geotechnical teams, the twin-ramp plus Railveyor configuration drives ramp geometry, power distribution design and ground support around continuous conveyor‑like haul paths.

    Myers Group picks Hitachi at Johnsons of Wellfield: productivity and fuel insights for ...

    Myers Group has deployed two Hitachi excavators – a heavy ZX530LCH-7 and a mid-sized ZX210LC-7 – at its Johnsons of Wellfield dimensional stone quarry in West Yorkshire, marking the first Hitachi units in its historically mixed fleet. Senior operations manager Ben Strickland reports a “significant reduction in fuel burn”, faster cycle times and better manoeuvrability compared with the outgoing excavators, alongside strong dealer aftersales support. Improved cab ergonomics and operator feedback suggest potential for longer productive shifts and reduced fatigue in primary extraction and aggregate handling.

    Globe 24-7, P&C and 3Pillars merger: talent pipeline insights for mine projects

    Globe 24-7, P&C Recruiting and HR, and 3Pillars Asia Pacific have merged to form a single recruitment and HR consulting provider focused on the global mining sector, combining direct candidate search, recruitment process outsourcing (RPO) and strategic HR advisory. The new group will operate across Asia Pacific, North and South America, Africa and Europe, targeting technical, operational and executive roles from pit to port. For mine owners and contractors, the move centralises sourcing for scarce skills in areas such as underground operations, processing plants and major project delivery.
