    Zijin Mining–Weir HPGR move at Akyem: comminution design notes for gold plant engineers

    September 8, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Weir has secured an order to supply two ENDURON® high-pressure grinding rolls (HPGRs) to Zijin Mining’s Golden Ridge operation at the Akyem gold mine in Ghana, as part of a brownfield optimisation of the existing comminution circuit. The HPGRs will be integrated into a flowsheet currently based on a conventional SAG and ball mill configuration that is struggling with higher ore competency. The move signals a shift towards more energy-efficient, dry grinding technology to debottleneck throughput and cut operating costs in a mature West African gold plant.

    Technical Brief

    • Increased ore competency at Golden Ridge implies higher Bond work index, driving the need for higher-pressure comminution.
    • Wear-part strategy for the ENDURON® units becomes critical, with liner change intervals affecting plant availability.

    Our Take

    Several recent Weir pieces in our coverage highlight the NEXT Intelligent Solutions platform and upgraded WARMAN mill circuit pumps; pairing those digital and pumping upgrades with HPGRs at Golden Ridge would allow Zijin to push for both lower specific energy and tighter process control in a single vendor ecosystem.

    Ferreyros’ 1,000th Caterpillar mining truck in Peru: fleet and haul design notes

    Ferreyros has delivered Peru’s 1,000th Caterpillar mining truck, a 410 short ton (372 t) payload Cat 798, to Compañía Minera Antamina for use at its copper-zinc operation at around 4,300 m elevation. The ultra-class truck will operate in high-altitude, low-oxygen conditions that challenge engine performance, tyre behaviour and haul road design, demanding close attention to cooling systems, fuel management and braking. For mine planners, the additional 372 t unit affects fleet dispatch, ramp geometry and crusher feed scheduling at one of Peru’s largest open pits.

    Critical minerals security vs 30‑year mine timelines: workflow lessons for engineers

    North America’s push to meet 2027 DFARS bans on Chinese-origin rare earth magnets is colliding with mine development timelines that can exceed 30 years from discovery to production, with 30–40% of that spent on PEAs, prefeasibility, feasibility and detailed engineering. AiMinr CEO Dr Ari Rostami argues the bottleneck lies in labour‑intensive, sequential study workflows, where changes in geology, mine design or prices can force months or years of rework across geotechnical, metallurgy, hydrology and financial models. AiMinr’s cloud platform links more than 50 AI agents via a central “orchestrated engine” to run these disciplines in parallel using deterministic algorithms, aiming to compress engineering phases from decades to years or even months.

    LGMG wide-body dump trucks: 10-year Frost & Sullivan lead and what it means for mines

    Frost & Sullivan has ranked Jinan-based LGMG as the global number one by annual sales volume of off-highway wide-body dump trucks for 10 consecutive years from 2016 to 2025. The consultancy used multidimensional, long-term data tracking across the global rigid and wide-body dump truck market to validate LGMG’s position. For mine operators, the finding signals continued strong field penetration of LGMG haul trucks, which may influence fleet standardisation, parts availability and competitive pricing against established rigid-frame OEMs.
