    Australian Strategic Materials quarterly lift: flowsheet and plant lessons for engineers

    Australian Strategic Materials quarterly lift: flowsheet and plant lessons for engineers

    First reported on Australian Mining

    30 Second Briefing

    Quarterly production at Australian Strategic Materials’ Dubbo rare earths and critical minerals project rose sharply in the March quarter, driven by higher-grade feed and improved plant availability at its pilot-scale metallisation and separation circuits. The company advanced engineering for its integrated zirconium, niobium, hafnium and rare earth oxide flowsheet, including optimisation of hydrometallurgical leach conditions and downstream solvent extraction stages. Across the sector, several Australian rare earths and battery metals developers reported step-outs from infill drilling and updated resource models, signalling continued momentum in project de-risking and feasibility work.

    Technical Brief

    • Hydrometallurgical optimisation work focused on leach conditions to improve impurity rejection and reagent efficiency.
    • Downstream solvent extraction stages were reconfigured to sharpen separation between light and heavy rare earth streams.
    • Pilot data are being used to refine equipment sizing and operating parameters for the planned commercial plant.

    Our Take

    The expanded NdFeB alloy offtake to Noveon in late 2025 suggests ASM’s quarterly production gains are likely being aligned with downstream magnet demand, which can strengthen its bargaining position in future long‑term contracts.

    Within our 1202 Mining stories and 2250 tag‑matched pieces on Projects and Sustainability, ASM stands out as one of the few Australian‑based players explicitly bridging upstream rare earths production with advanced alloy manufacturing, which may influence how other local critical minerals projects frame their value‑addition strategies.

    XEMC ultra-class full battery trucks: pit design and power notes for mine planners

    China’s Xiangtan Electric Manufacturing Corporation (XEMC) is reporting sustained demand for its ultra-class, fully battery-electric rigid mining trucks, positioning them alongside early deployments such as Caterpillar’s 793 XE “Early Learner” units in the US and Australia and Hitachi’s EH4000 battery trolley fleet at FQM’s Kansanshi mine. XEMC’s trucks target the >220 t payload class traditionally dominated by diesel and diesel–electric haulage. For mine planners and geotechnical teams, large-scale adoption of such full-battery fleets will drive changes in pit ventilation design, ramp power distribution, and haul road geometry around charging or swap stations.

    Engineered transfer points: debottlenecking plant throughput for mine engineers

    Engineered transfer points are becoming central to plant performance as mines push higher throughput, with Weba Chute Systems’ Technical Director Dewald Tintinger warning that poorly designed chutes can disproportionately constrain material flow and equipment life. Misaligned or under-designed chutes accelerate liner wear, increase blockages and spillage, and drive up dust emissions, directly affecting conveyor availability and downstream crushers and screens. Better-controlled flow paths and impact angles at transfer points are now being used as a primary lever for debottlenecking existing plants without major capital upgrades.

    Schlam global expansion: load and haul design options and GET insights for mine engineers

    Load and haul attachment specialist Schlam is expanding its global operating model by adding a wider range of mining buckets, new high-quality ground engaging tools (GET) and installation kits for truck bodies and buckets. The move consolidates all product categories – including truck trays, buckets and GET – under a strengthened global leadership team focused on international market development. For mine operators, the broader portfolio and standardised installation kits signal more options for matching tray and bucket designs to specific loading tools and material conditions.
