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.

Cementation Americas, Cementation Africa and Terra Nova Technologies (TNT) have entered a strategic ownership transition that commercially closed on 19 May, placing control of these underground mining, EPCM and materials handling specialists under a consortium led by South African investment group Differential Capital by 25 June 2026. The deal includes Merit Consultants International within Cementation Americas, consolidating shaft sinking, raiseboring, underground construction and overland conveyor expertise under a single investment umbrella. For mine developers, the move signals a more integrated offering across design-build, underground infrastructure and bulk materials handling on a global project basis.

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.
