    MeiTeng’s 15th mobile XRT in Tibet: reliability lessons for high-altitude mines

    MeiTeng’s 15th mobile XRT in Tibet: reliability lessons for high-altitude mines

    First reported on International Mining – News

    30 Second Briefing

    MeiTeng’s 15th wheel-mounted mobile XRT ore sorting system has completed 24 months of continuous operation at the Zhalixikang lead-zinc polymetallic mine in Longzi County, Tibet, working at an altitude of nearly 4,800 m since its 2024 commissioning. The unit has just finished sorting at one mining face and is being relocated to the next, showing that containerised, trailer-based XRT plants can maintain stable performance under extreme elevation, low-oxygen conditions and frequent moves between faces.

    Technical Brief

    • Wheel-mounted configuration allows rapid relocation between working faces without fixed civils or foundations.
    • Containerised XRT modules likely integrate crusher, feeder, sorter and conveyors on a single trailerised train.
    • Operation at ~4,800 m implies derated diesel and cooling performance, demanding conservative power sizing.
    • Low-oxygen, low-pressure conditions increase heat load on X-ray tubes and electronics, stressing thermal management design.
    • Trailer-based plant reduces ore rehandling distances, cutting haulage fuel burn and face stockpile requirements.
    • Such high-altitude deployments inform derating factors and maintenance intervals for future mobile XRT fleets in plateau terrains.

    Our Take

    MeiTeng’s XRT rollout at the Zhalixikang lead-zinc polymetallic mine in Tibet mirrors its March 2026 deployment of five XRT systems for Tajik-China Mining Co’s lead-zinc operations in Tajikistan, suggesting the company is standardising a lead/zinc-focused ore-sorting offering across high-altitude and remote sites.

    Across our 1305 Mining stories, lead and zinc appear far less frequently than iron ore, copper or gold, so repeated coverage of MeiTeng’s lead-zinc projects in Tibet and Tajikistan signals that ore sorting is becoming a key lever for marginal polymetallic operations rather than just coal preparation plants.

    Sandvik IEC 62443-4-1 ML3: cybersecurity implications for intelligent mines

    Sandvik has secured IEC 62443-4-1 Maturity Level 3 certification for its secure product development lifecycle, making it one of the first mining OEMs to reach this cybersecurity benchmark. The independently audited ML3 rating confirms that threat modelling, secure coding, vulnerability management and patch processes are systematically built into the design and maintenance of its intelligent mining equipment and digital systems. For mines deploying connected fleets, autonomous loaders and remote drilling rigs, this signals stronger protection against cyber intrusion at both equipment and control-system level.

    BME’s VIPERTRON electronic initiation system: design and timing notes for mine engineers

    BME has launched the VIPERTRON electronic initiation system, a lightweight, compact blasting solution designed for agile deployment in quarries and surface mines using robust radio-frequency communication between field units and the blasting control. The system targets operations still using NONEL by offering tighter timing accuracy and more consistent blast performance, while maintaining simple, portable hardware for crews working in constrained benches and multiple small shots. For engineers, the key shift is towards electronic timing control without the complexity and bulk of traditional wired electronic detonator systems.

    Brightstar’s Laverton expansion corridor: mine planning and haulage lens for engineers

    Brightstar Resources has secured five exploration licences comprising Panther Metals’ Mikado project around its new Laverton processing plant in Western Australia under a 100 per cent binding tenement sale agreement. The deal consolidates tenure immediately adjacent to the planned processing hub, giving Brightstar direct control over near-plant feed sources rather than relying on satellite ore trucking. For mine planners and geotechs, the enlarged footprint enables integrated pit design, waste dump siting and haulage optimisation across a contiguous land package.
