    McLanahan’s growing might in mining: QUICKCHANGE filter press gains for plant engineers

    McLanahan’s growing might in mining: QUICKCHANGE filter press gains for plant engineers

    First reported on International Mining – News

    30 Second Briefing

    McLanahan Corporation and its Italian sister company Diefenbach have launched the patent-pending QUICKCHANGE™ system for filter presses, introduced in March 2025 and engineered to cut maintenance time through faster, simpler and safer plate change-outs. The system targets high-throughput mining dewatering circuits where conventional filter press maintenance can cause extended downtime and manual handling risk. For plant engineers, QUICKCHANGE™ signals further mechanisation of filter press servicing, with potential to tighten maintenance windows and improve availability without major changes to existing dewatering layouts.

    Technical Brief

    • QUICKCHANGE™ is a patent-pending mechanical system integrated directly into Diefenbach/McLanahan filter press frames.
    • The system is designed to be retrofittable to existing Diefenbach presses without major structural modification.
    • Plate handling is mechanised to reduce manual lifting and pinch-point exposure during change-out operations.
    • McLanahan cites reduced need for scaffolds or temporary platforms around the press during maintenance.
    • The design targets large mining presses where plate packs can exceed several tonnes in aggregate mass.
    • QUICKCHANGE™ was jointly engineered between McLanahan’s Hollidaysburg, PA facility and Diefenbach’s Medolago, Italy plant.
    • Integration with OEM control systems allows interlocks to prevent motion while operators are in the hazard zone.
    • For high-throughput mines, such mechanised change-out systems support tighter lock-out/tag-out windows and clearer task demarcation.

    Our Take

    In our coverage of mining equipment, post-acquisition product launches on a roughly two-year cadence, as seen here between the 2023 deal and the March 2025 introduction, usually signal that integration of engineering teams and IP has progressed beyond simple branding to genuine platform redesign.

    BMO on Canada’s C$120bn mining pipeline: capex and project signals for engineers

    Canada is positioning for a larger share of global mining capital as BMO Global Metals & Mining flags C$120 billion in planned project spending in Natural Resources Canada’s 10‑year Major Projects Inventory and forecasts more than 11% annual growth in development capex over the next two years. BMO urges investors to shift from purely upstream projects towards domestic copper smelting and refining, battery precursor materials, rare earth separation and by‑product capture to build end‑to‑end supply chains. The bank also points to separating mine and infrastructure financing, tapping under‑allocated Canadian pension assets (C$4.5 trillion), and targeting new districts from BC to Ontario’s Ring of Fire and Nunavut.

    US DOE $73M Mine of the Future funding: key testbed insights for engineers

    The US Department of Energy has awarded US$73 million through its Mine of the Future initiative to four projects creating national-scale mining testbeds in West Virginia, Colorado, Arizona, Missouri and Texas. Innovative Wireless Technologies will integrate underground and surface sites in Julian, Blacksburg and Idaho Springs to validate next‑generation digital, connectivity and automation systems, while the University of Arizona and University of Missouri will build underground and comminution proving grounds focused on electrification and energy management. Southern Methodist University will repurpose a heavily instrumented Navasota drilling site into a “synthetic mine” for repeatable testing of drilling, sensing and autonomous workflows, aiming to de‑risk commercial deployment.

    Mining leads Canadian PM’s C$1T pitchbook: project finance signals for engineers

    Mining projects dominate Prime Minister Mark Carney’s leaked C$1 trillion, five‑year investment pitchbook, with 63 of 167 opportunities spanning lithium, nickel, graphite, rare earths, gold and copper, and including proposals such as Canada’s first uranium refining and conversion plant in more than 40 years. Confirmed entries range from LithiumBank’s Boardwalk lithium brine project in Alberta, with 5.2 million measured and indicated tonnes LCE at 81.6 mg/L, to Surge Copper’s Berg copper‑molybdenum project, scoped for a 28‑year life and 176 million lb copper per year. Despite a 75% year‑on‑year rise to C$10.1 billion in TSX/TSXV mining equity raisings, pension and sovereign funds remain cautious on finite‑life mines, making long‑life assets and midstream processing plants more likely to secure capital.
