    Metso’s primary crushing progression: selection notes for mine planners and engineers

    Metso’s primary crushing progression: selection notes for mine planners and engineers

    First reported on International Mining – News

    30 Second Briefing

    Metso has expanded its primary crushing line-up with three new machines: the Primarok™ next‑generation primary gyratory, the Optirok™ evolved primary jaw crusher, and the Durarok™ large sizer for high-capacity installations. The range targets different front‑end configurations, from deep open pits feeding large gyratories to operations preferring jaw‑based plants or low‑height sizer stations. For mine planners and process engineers, the trio broadens options for matching crusher type to ROM fragmentation, bench geometry and downstream throughput constraints.

    Technical Brief

    • Primarok™ is positioned as Metso’s next generation of its existing primary gyratory crusher line.
    • Optirok™ is described as an evolution of Metso’s established primary jaw crusher platform, not a clean-sheet design.
    • Durarok™ introduces large sizer technology into Metso’s primary crusher portfolio, extending beyond its traditional gyratory/jaw offering.

    Our Take

    Across our recent Mining coverage, Metso features repeatedly in equipment and service stories, signalling that its primary crushing line is being backed by parallel investments in research capability, logistics and aftermarket support rather than as a standalone product push.

    Metso’s new service centre in Prince George and the DHL 3PL deal in Australia indicate that the company is building regional support density around its crushing portfolio, which is likely to reduce perceived risk for greenfield projects specifying large primary units in remote hubs.

    PLS Pilgangoora 22-sorter TOMRA contract: process design notes for engineers

    TOMRA Mining has secured a contract from Pilgangoora Operations Pty Ltd, a PLS Group subsidiary, to supply 22 sensor-based ore sorters for the P2000 Expansion Project at the Pilgangoora lithium operation in Western Australia. The installation is part of PLS’ pre-Final Investment Decision early works, signalling commitment to large-scale sorting ahead of full project sanction. For process engineers, the move points to increased reliance on front-end sensor-based separation to upgrade run-of-mine feed and manage lithia grade variability before downstream concentration.

    Macmahon’s 42‑month Telfer Gold Mine extension: planning notes for project teams

    Macmahon Contractors has secured a 42‑month extension to provide contract mining services at Greatland Resources’ Telfer Gold Mine in Western Australia, valued at A$485 million over the term. The deal locks in a multi‑year mining services pipeline at one of the state’s major gold operations, supporting continuity of fleet deployment, workforce planning and site-based maintenance. Contractors and suppliers can expect sustained demand for open-pit and underground support services, consumables and rebuilds tied to Telfer’s existing mine plan.

    Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers

    Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
