    Metso Grande Series high-capacity screens: circuit design notes for plant engineers

    Metso Grande Series high-capacity screens: circuit design notes for plant engineers

    First reported on International Mining – News

    30 Second Briefing

    Metso has launched its Grande Series™ of high-capacity stationary screens, introducing three new types – GLH, GMF and GFF – for demanding mining and aggregates applications. The range targets high-throughput, multi-deck screening duties where conventional units struggle with capacity, blinding or large feed size. For plant designers and process engineers, the new models expand options for fixed crushing and screening circuits needing greater tonnage and sharper separation without moving to multiple parallel screens.

    Technical Brief

    • Grande Series™ units are stationary screens, targeting fixed crushing and screening plant layouts.
    • GLH, GMF and GFF models are differentiated by screening duty and motion type for process optimisation.
    • Designs are described as “high-capacity”, aimed at single-machine duties rather than multiple parallel screens.
    • Metso positions the series for both mining and construction aggregates circuits, covering hard rock and softer ores.
    • Engineering focus is on productivity and efficiency, implying reduced recirculating loads and sharper size classification.
    • Units are specified for “demanding” screening, indicating suitability for abrasive materials and high-impact feed conditions.

    Our Take

    Metso’s Grande Series launch comes alongside other recent process-equipment moves in our coverage, such as the circa-€55 million package for Harmony’s Eva copper project, signalling a push to lock in full flowsheet positions rather than just stand‑alone machines.

    With both the Grande Series and the third‑generation OKTOP® Cooling Tower appearing in recent Metso items, the company is clearly targeting higher-capacity, more compact plant layouts, which will appeal to brownfield operators trying to debottleneck without major civils work.

    Across the 407 tag‑matched ‘Projects’ and ‘Product’ pieces in our database, Metso appears frequently, suggesting that OEM selection for new screening lines like Grande Series is increasingly consolidating around a few large suppliers with integrated service offerings.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
