    Weir’s WARMAN pumps at Xizang copper mine: slurry and tailings notes for engineers

    Weir’s WARMAN pumps at Xizang copper mine: slurry and tailings notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Weir has secured a multimillion‑dollar contract with a major Chinese non‑ferrous metals company to supply WARMAN® pumps for the Phase III expansion of a Xizang copper mine. The package comprises two WARMAN MCR® 450 cyclone feed pumps and nine WARMAN AHPP 20/18 tailings transfer pumps serving the grinding circuit and tailings system. For engineers, the deal signals continued preference for high‑capacity slurry and tailings pumping solutions in large‑scale Chinese copper concentrator expansions.

    Technical Brief

    • Package combines cyclone feed and tailings transfer duties within a single coordinated pump supply.
    • MCR® 450 units are configured as cyclone feed pumps, indicating high-throughput grinding and classification circuits.
    • AHPP 20/18 pumps are assigned to tailings transfer, pointing to a dedicated high-head disposal line.
    • Centralised sourcing of 11 large slurry pumps simplifies spares, wear‑part inventory and maintenance planning.

    Our Take

    Recent coverage of Weir’s Q1 2026 results highlighted a growing pipeline of large equipment projects for mine debottlenecking and brownfield expansion; securing multimillion‑dollar WARMAN pump work at a copper site like Xizang suggests that copper remains one of the more active drivers of that order book.

    The simultaneous expansion of Weir’s Heavy Bay Foundry and its new 14,500 sq.m Perth facility in Hazelmere indicates that the company is building manufacturing and service capacity to support exactly these kinds of large WARMAN MCR and AHPP pump packages for high‑throughput copper circuits.

    EPC Groupe–Sabodala contract: blasting capacity and slope control insights for engineers

    EPC Groupe, through EPC Mineex Sénégal, has secured a five-year explosives supply and services contract with Endeavour’s Sabodala gold mine in Senegal, valued at about €10 million per year at full run rate. The deal covers bulk explosives and blasting support for one of West Africa’s largest open-pit gold operations, signalling a step-up in local emulsion manufacturing, on-bench services and blast design capability. For mine planners and geotechnical teams, the contract points to stable high-volume blasting capacity, supporting consistent fragmentation and slope performance over the medium term.

    Haultrax HX Coach in FMS: operational coaching and dispatch insights for mine teams

    Haultrax is integrating its on-site operational coaching directly into its Fleet Management System with the launch of HX Coach at IMARC 2026. The module is designed to embed real-time operator guidance and training logic into haulage fleet dispatch, moving beyond traditional FMS reporting towards in-cab behavioural feedback and decision support. For mine operators, this signals a shift from separate coaching programmes to a software-native approach that can systematically influence truck and shovel performance at scale.

    IsaMill at 30: fine grinding efficiency lessons for concentrator engineers

    Glencore Technology is marking 30 years of the IsaMill fine grinding mill, first developed by Mount Isa Mines and NETZSCH to tackle complex, ultra-fine regrind duties in base metal circuits. The horizontal, high-intensity stirred mill has since been deployed in more than 130 installations globally, often replacing ball mills in the sub-20 µm range to cut specific energy consumption and increase throughput. Recent IsaMill developments focus on larger M-series units, improved ceramic media wear performance and integration with modern flotation and coarse particle recovery flowsheets.
