    FLS semi-mobile crushing at Vale’s S11D: IPCC layout notes for mine planners

    FLS semi-mobile crushing at Vale’s S11D: IPCC layout notes for mine planners

    First reported on International Mining – News

    30 Second Briefing

    FLSmidth has installed a large semi-mobile crushing station with sizer technology at Vale’s S11D Serra Sul iron ore operation in Brazil, with the first 26 m-high module commissioned in Area 5 to open new mining blocks. The semi-mobile design allows relocation as the pit advances, reducing truck haul distances to the conveyor network and supporting S11D’s high-throughput, low-strip-ratio mine plan. For mine planners and process engineers, the setup signals continued shift towards in-pit crushing and conveying (IPCC)-style layouts at large-scale iron ore operations.

    Technical Brief

    • First semi-mobile station module stands 26 m high, indicating multi-level structural and access requirements.
    • Structural steelwork and foundations must accommodate relocation loads as well as normal operating vibration and impact.
    • Semi-mobile concept reduces need for permanent retaining structures and deep foundations compared with fixed plants.

    Our Take

    Vale’s S11D iron ore complex in Brazil already features heavily in our Mining coverage as a margin-critical asset, so deploying a 26 m-high semi-mobile crushing module here signals that FLSmidth’s solution is being proven at one of the world’s benchmark bulk operations rather than at a peripheral site.

    With iron ore again prominent in recent valuation pieces on diversified majors, any throughput or cost gains from the new crushing station at S11D are likely to have an outsized impact on Vale’s earnings sensitivity compared with smaller Brazilian operations.

    Fluor’s 2025 acquisition of FLSmidth’s Overland Conveyor Products Group suggests that future expansions or replications of this semi-mobile crushing concept at Vale sites could see a more fragmented supply chain, with crushing and conveying packages no longer coming from a single OEM group.

    JOEST Australia’s Pilgangoora expansion order: design and wear notes for mine engineers

    JOEST Australia has secured the largest order in its history from Pilgangoora Operations Pty Ltd for the PLS P2000 Expansion Project at the Pilgangoora hard rock lithium mine in Western Australia. The contract covers multiple vibrating screens, feeders and a primary grizzly, building on JOEST’s previous scope at the site. With the P1000 Expansion Project due to complete in 2025, the new package signals further scaling of front-end crushing and screening capacity, with implications for equipment sizing, wear-liner selection and maintenance planning in high-throughput lithium circuits.

    BHP’s first Olympic Dam block cave resource: design and cave stability notes for engineers

    BHP has declared a first underground block cave resource at Olympic Dam in South Australia, reporting 10,730 Mt at 0.59% Cu, 0.19 kg/t U3O8, 0.21 g/t Au and 1 g/t Ag in its operational review to 30 September 2026. The scale and grade support long-life mass mining beyond the existing sublevel open stoping, with block caving likely to demand extensive footprint development, cave propagation monitoring and high-capacity materials handling. Geotechnical teams will be focused on managing cave stability in the complex copper-uranium breccia-hosted system and controlling subsidence above critical surface infrastructure.

    FLANDERS hybrid cabinet on Komatsu 930E at Belle Ayr: lifecycle gains for mine fleets

    FLANDERS has completed a claimed world-first installation of its hybrid-electric control cabinet on a diesel-electric Komatsu 930E haul truck operated by Eagle Summit Resources at the Belle Ayr coal mine in Wyoming. The retrofit cabinet replaces legacy electric-drive controls to address haul truck obsolescence while retaining the existing diesel-electric drivetrain. For mine operators, the approach signals a pathway to extend 930E fleet life and prepare for future higher-level electrification without full truck replacement.
