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.

Normet’s battery-electric fleet at Rio Tinto’s Oyu Tolgoi underground copper-gold mine in Mongolia is being used at scale to prove full-cycle electrification in a deep, block-cave operation with long ramp hauls and high ambient temperatures in the South Gobi Desert. Multiple BEV platforms, including concrete sprayers, scalers and utility vehicles, are operating in extensive development and production areas, replacing comparable diesel units in demanding ground conditions. Early data on energy use, heat load and maintenance intervals is informing ventilation design, power distribution planning and future fleet selection for large underground projects.

Brazil Potash has awarded a second Front-End Engineering Design contract for mine shafts and underground development at its Autazes potash project in Amazonas State, Brazil, to WSP UK, with Redpath Deilmann as subconsultant for the shaft scope. The FEED package will define shaft configuration, sinking methodology and underground access layouts for the planned solution mining-style potash operation, de-risking detailed design and construction tendering. For geotechnical and shaft specialists, the appointment signals early engagement on ground control, lining design and water inflow management in challenging Amazon basin conditions.
