    Metso’s holistic mineral processing: circuit design lessons for plant engineers

    Metso’s holistic mineral processing: circuit design lessons for plant engineers

    First reported on Australian Mining

    30 Second Briefing

    Metso is promoting a “whole-of-circuit” approach to mineral processing, linking equipment such as vibrating pan feeders, multi-deck screens and high-pressure grinding rolls to optimise throughput and energy use rather than individual unit performance. By integrating digital tools like Metso Metrics and advanced process control with wear monitoring on crushers, mills and screens, the company aims to stabilise feed, reduce recirculating loads and extend liner life. For plant engineers, the message is to redesign and tune circuits as systems, not as isolated machines.

    Technical Brief

    • Metso’s vibrating pan feeders are configured to deliver uniform burden depth and velocity onto downstream screens.
    • Multi-deck screens are selected and tuned to match crusher and HPGR capacity, minimising oversize recycle.
    • Wear-life data from crusher and mill liners is fed back into circuit design to adjust operating windows.
    • Advanced process control uses real-time feed size and hardness signals to adjust crusher gaps and mill speeds.
    • Condition monitoring on bearings and drives enables planned shutdowns aligned across the entire comminution line.
    • Circuit redesign work includes re-routing conveyors and chutes to remove bottlenecks and reduce transfer-point spillage.
    • For brownfield plants, the approach is framed as phased debottlenecking projects rather than single-machine upgrades.

    Our Take

    Metso’s recent acquisition of Newcastle-based MRA Automation in Australia suggests it is building local automation and control capability that can underpin the kind of ‘holistic’ mineral processing optimisation this piece is likely advocating.

    Across our mining coverage, Metso increasingly appears not just as an equipment vendor but as a full flowsheet and plant-delivery supplier, as seen in the €128 million gold processing plant package for Ma’aden, which reinforces the strategic push towards integrated processing solutions highlighted here.

    The use of Metso’s Concorde Cell flotation at Barrick’s Lumwana copper expansion shows that major operators are already adopting Metso’s advanced separation technologies at scale, giving practical backing to any discussion of end-to-end process thinking in this Australian-focused article.

    Safety in underground mining: operational design lessons for project teams

    Safety in underground mining is framed by Johan Mostert, SHEQT Executive at Redpath Africa, as a core operational discipline rather than a standalone compliance task, requiring integration into planning, communication, decision-making and daily task execution. He stresses that rapidly changing geotechnical conditions and production pressure can quickly erode controls if safety is not embedded in frontline behaviours and supervisory routines. For engineers and managers, this points to designing procedures, shift plans and reporting systems where hazard identification, ground control checks and clear communication protocols are treated as primary production inputs.

    Volvo Mining entity: autonomy integration and fleet planning notes for engineers

    Volvo Group is creating a dedicated Volvo Mining business to consolidate sales of Volvo-branded haul trucks, construction equipment and autonomous solutions into a single global mining-focused structure. The entity will integrate on-road and off-road fleets with autonomy platforms across load–haul, pit and haul road applications, targeting large open-pit operations as well as smaller contract miners. For mine planners and fleet engineers, this signals tighter OEM integration between conventional diesel fleets and emerging autonomous haulage and support equipment within one commercial and support framework.

    Booyco Electronics Missing Person Locator: design and safety notes for mine teams

    Booyco Electronics has launched its Missing Person Locator (MPL), an underground personnel tracking system designed to locate workers rapidly during emergencies and meet tighter South African mine safety legislation. The MPL integrates with existing Booyco collision avoidance and cap-lamp tags to provide real-time positional data in complex tunnel networks, addressing delays and blind spots in conventional tag board and muster-based procedures. Faster localisation in the “golden hour” after an incident allows more targeted rescue deployment and supports formalised search-and-rescue protocols in deep, extensive workings.
