Metso in the critical minerals race: flowsheet design lessons for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Metso executives David Tulloch, Duncan Wyatt and Guillaume Lambert outline how the company is targeting critical minerals flowsheets with integrated crushing, grinding and flotation circuits, combined with smelting test work at its Pori Research Centre. The approach uses ore-specific pilot campaigns, digital process control and modular equipment packages to raise recovery and reduce energy per tonne, particularly for complex nickel, lithium and rare earth ores. For mine planners and process engineers, the message is tighter ore characterisation upfront and more standardised, scalable plant designs across greenfield and brownfield projects.
Technical Brief
- Smelting test work is concentrated at Metso’s Pori Research Centre, enabling integrated bench-to-pilot campaigns.
Our Take
Metso’s critical minerals work in Australia sits alongside a run of recent equipment contracts, including the Eva copper project in Queensland, signalling that miners are increasingly tying greenfield designs to OEM-led efficiency packages rather than piecemeal kit selection.
Our database shows several Metso items this quarter on new product lines and facilities – from the Grande Series mining screens to the Pittsburgh bulk-handling hub – suggesting the Pori Research Centre is part of a wider push to control performance across the full crushing–screening–materials handling chain for critical minerals flowsheets.
Although this piece focuses on critical minerals in Australia, Metso’s compact pellet plant order for Greta Energy in India highlights that its process-optimisation work is being applied across both ferrous and non-ferrous value chains, which can de-risk supply for multi-commodity producers exposed to battery and steel markets alike.
