    Navoi’s ‘cyclic-flow’ IPCC at Muruntau: design and ramp implications for mine planners

    Navoi’s ‘cyclic-flow’ IPCC at Muruntau: design and ramp implications for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Navoi Mining & Metallurgical Company has commissioned a new “cyclic-flow” in-pit crushing and conveying (IPCC) system on the southern flank of the Muruntau open pit to optimise ore transport to permanent and temporary stockpiles. The complex integrates truck haulage to an in-pit crusher with belt conveyors for continuous ore transfer, reducing reliance on long uphill truck ramps and diesel-intensive haul cycles. For mine planners and geotechnical teams, the layout fixes pit exit points and ramp geometries, influencing future pushback design and slope stability management around conveyor corridors.

    Technical Brief

    • Cyclic-flow complexes at Muruntau are being rolled out as part of a wider production expansion.
    • NMMC frames the southern flank installation as an “investment project” directly tied to higher precious metal output.
    • Ore routing explicitly caters for both permanent stockpiles and short-term temporary storage facilities within the pit logistics.
    • The complex is described as one of several cyclic-flow systems “widely applied” across the Muruntau operation.
    • Project scope is limited to ore transport optimisation; no mention of waste or overburden handling integration.
    • Language used by NMMC suggests further cyclic-flow IPCC complexes are planned as the open pit deepens.
    • For other large open pits, similar cyclic-flow layouts could lock in long-term ramp and haulage geometries.

    Our Take

    Navoi Mining & Metallurgical Company’s recent upgrade to a ‘BB’ long-term credit rating suggests that large-scale infrastructure such as the cyclic-flow IPCC at the Muruntau deposit is being delivered against a backdrop of improving access to external finance, which can support further pit expansion or additional material handling phases.

    Within our database of precious metals project coverage, Muruntau stands out as one of the few long-life gold operations where in-pit crushing and conveying is being systematically rolled out, signalling that NMMC is positioning the asset to stay competitive on unit mining costs as stripping ratios increase.

    For practitioners, the combination of a precious metals orebody and a fully integrated IPCC system at Murunatu pit is notable because most IPCC deployments in our coverage are tied to bulk commodities; this raises the bar for other high-tonnage gold operations evaluating whether similar capital-intensive systems can be justified on ore value rather than volume alone.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
