    Vibratory screening of mined materials: mesh and maintenance lessons for engineers

    Vibratory screening of mined materials: mesh and maintenance lessons for engineers

    First reported on Australian Mining

    30 Second Briefing

    Higher efficiency vibratory screening in mines is being driven by optimised mesh selection, correct vibrator sizing, and improved access to screen vibrators as critical wear parts. Martin Engineering’s Susie O. Bartoli stresses matching vibration frequency and amplitude to particle size distribution and moisture content, along with using appropriate wire diameters and aperture geometries to reduce blinding and carryover. Ergonomic maintenance access to vibrator assemblies and tensioning systems is framed as essential to cut downtime and manual handling risks on multi-deck screening stations.

    Technical Brief

    • Screen vibrators are treated as consumable wear parts, requiring scheduled replacement within planned shutdown windows.
    • Ergonomic access platforms around multi-deck screens reduce working-at-height exposure during vibrator and mesh change-outs.
    • Bolt-on vibrator assemblies allow removal with mechanical aids, limiting manual handling of high-mass components.
    • Standardised vibrator models across screening stations simplify spares inventory and reduce change-out time under permit conditions.
    • Clear isolation points and lock-out/tag-out provisions at each vibrator are emphasised for maintenance safety.
    • Guarding around moving screen components is framed as needing tool-only removal and positive reattachment checks.
    • Guidance links screening design decisions directly to compliance with site-specific safe work procedures and risk assessments.

    Our Take

    Within our 353 Mining stories, Australia-based coverage often clusters around haulage and processing plant upgrades, so a focus on vibratory screening suggests operators are now looking for incremental efficiency gains in secondary circuits rather than only in primary crushing or fleet automation.

    Martin Engineering appears mainly in our database in the context of bulk material handling and dust control, so its push into screening efficiency in Australia likely reflects a strategy to bundle safety, spillage control and throughput optimisation as a single value proposition to mine operators.

    Among the 725 tag-matched pieces on Projects, Safety and Product, relatively few deal with screening hardware, which means mines adopting newer mesh and vibration configurations can still gain a competitive edge in uptime and maintenance exposure compared with more widely discussed conveyor or truck safety upgrades.

    Scope Systems cyber attack: resilience and risk lessons for mining IT teams

    A ransomware attack on Perth-based Scope Systems’ Pronto Xi ERP cloud stack disrupted dozens of mining customers, including Northern Star Resources and Evolution Mining, in what MM‑ISAC’s Rob Labbe calls the broadest single third‑party cyber event the sector has seen. Scope says client servers were restored from backups and not directly accessed, but admits internal data was exfiltrated and has not disclosed the attack vector, raising questions about visibility at hypervisor, storage and backup layers. The incident spotlights how multi‑tenant vCenter/ESXi environments, VM cloning and snapshot abuse—already used by groups like Akira—could expose integrated exploration, production and maintenance data across more than 400 Pronto Xi‑reliant mining operations.

    Newmont’s Red Chris underground expansion: block cave design and capex notes for engineers

    Newmont’s Red Chris mine in British Columbia has secured an amended Environmental Assessment Certificate and Mines Act permit, allowing a shift from open-pit to underground block caving and extending operations into the mid-2040s. The copper-gold porphyry deposit in the Golden Triangle hosts an estimated 20 million oz of gold and 13 billion lb of copper, with the block cave expected to lift Canada’s copper output by about 15%. The project entails several billion dollars in capital, around 1,800 construction jobs and roughly 1,500 operating roles at peak.

    Goldman cuts gold price forecast to US$4,900: planning notes for mine projects

    Goldman Sachs has cut its end‑2026 gold price forecast by US$500/oz to US$4,900/oz after the US Federal Reserve, under new chair Kevin Warsh, signalled a hawkish shift that has pushed market-implied December rate hike odds to 87%. Spot gold has already fallen to about US$4,100/oz, down 27% from its near‑US$5,600/oz January peak, with three consecutive monthly losses between March and May and a 4% year‑to‑date decline. Goldman warns a 2026 year‑end target as low as US$4,400/oz is possible if rates rise, partly offset by ongoing central‑bank buying of roughly 50 tonnes/month this year and 40 tonnes/month next year.
