    CITIC HIC semi-mobile crusher at Duobaoshan: design and throughput notes for mine planners

    June 19, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    A PSZ3000-B semi-mobile gyratory crushing station, independently designed and built by CITIC Heavy Industries in Luoyang, has completed no-load and load commissioning at Zijin Mining’s Phase II expansion of the Duobaoshan copper-molybdenum mine in Heilongjiang, with all performance indicators meeting design standards. The semi-mobile unit is configured as a primary crusher station for the expanded open pit, allowing truck-fed in-pit crushing with conveyor transfer to downstream processing. For mine planners and plant engineers, the successful commissioning confirms Chinese-built large semi-mobile gyratory technology as a viable option for high-throughput greenfield and brownfield expansions.

    Technical Brief

    • No-load and load commissioning sequence validates structural vibration behaviour of the semi-mobile steel superstructure and foundations.
    • CITIC HIC’s in-house design allows mechanical, electrical and control systems to be integrated under a single OEM.
    • Local Chinese manufacture reduces lead time and logistics complexity versus importing large gyratory stations to Heilongjiang.
    • Successful deployment at Duobaoshan provides a domestic reference plant for similar large open-pit mining expansions in China.

    Our Take

    With both Duobaoshan in Heilongjiang and Julong in Tibet using CITIC Heavy Industries crushing technology for copper, our database suggests Zijin is consolidating a single OEM for front‑end comminution across key Chinese copper hubs, which typically simplifies spares and maintenance planning.

    Deploying a semi‑mobile station at a second‑phase expansion of Duobaoshan gives Zijin more optionality to follow orebody extensions without full greenfield civils, a configuration that in other copper projects has been used to defer or stage capital while still lifting throughput.

    LEEA GLAD procurement survey: compliance and lifecycle insights for mine teams

    LEEA has launched a procurement-focused survey to feed into a new white paper scheduled for release on Global Lifting Awareness Day (GLAD) on 2 July 2026, with details hosted on the updated campaign site globalliftingawarenessday.com. Targeted at stakeholders who specify or purchase cranes, hoists, slings and other lifting accessories, the initiative centres on the theme “Not all lifting equipment is…”, aiming to capture how compliance, whole‑life cost and inspection regimes are currently weighted in buying decisions. Mining owners, EPCMs and contractors can use the findings to benchmark procurement practices against industry expectations and tightening safety standards.

    Hitachi EH5000 100,000‑hour milestone at Lumwana: capex and fleet life notes for planners

    Three 296 t class Hitachi EH5000 rigid dump trucks at Barrick’s Lumwana copper mine in Zambia have each passed 100,000 operating hours, an unusually high lifecycle for ultra-class haulage equipment in hard-rock copper operations. The milestone, marked at a joint Barrick–Hitachi recognition ceremony, points to effective component rebuild strategies, condition-based maintenance and strong dealer support for the EH5000 fleet. For mine planners and maintenance teams, it signals potential to extend truck life beyond typical replacement cycles, with implications for capex timing and fleet renewal strategies.

    Zijin’s 290 battery trucks at Wulagen: ventilation and design notes for mine planners

    Zijin Mining Group is rolling out a 290-strong battery electric truck fleet at its Wulagen lead-zinc mine in Wuqia County, Xinjiang, replacing conventional diesel haulage and creating one of the largest single-site BEV truck deployments worldwide. The mine, operated by Xinjiang Zijin Zinc, is shifting to fully electric underground and surface haul routes, relying on high-capacity battery packs and fast-swapping or fast-charging systems to keep utilisation high. For mine planners and geotechnical teams, the move reduces diesel ventilation demand and heat load, potentially allowing deeper or denser development with lower airflow requirements.
