Metso’s holistic mineral processing: circuit design lessons for plant engineers
Reviewed by Joe Ashwell

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.
