    FLS BHQ iron ore beneficiation order: HPGR and milling implications for engineers

    FLS BHQ iron ore beneficiation order: HPGR and milling implications for engineers

    First reported on International Mining – News

    30 Second Briefing

    FLS has secured multiple repeat contracts to supply key technologies for a Banded Haematite Quartzite iron ore beneficiation plant in South Asia, centred on a High-Pressure Grinding Roll described as the largest of its kind. The package also includes nine of the world’s largest stirred media mills, indicating a flowsheet geared to fine grinding of low-grade BHQ ore into premium concentrate. For process engineers, the scale of HPGR and stirred milling points to high throughput, energy-intensive comminution with significant implications for wear materials, water balance and tailings handling.

    Technical Brief

    • Vendor standardisation on HPGR and stirred mills should simplify spares, liner inventory and maintenance planning.
    • Process design must accommodate BHQ-specific hardness and abrasiveness, driving selection of high-wear-resistant materials.
    • Fine grinding duty will require tight process water control and likely high-rate or paste tailings management.
    • Large-scale stirred milling at BHQ sites could set a reference flowsheet for other low-grade hematite-quartzite deposits.

    Our Take

    FLS’s recent joint venture in Uzbekistan to service copper, gold and uranium operations, together with this south Asia iron ore contract, signals a deliberate push into emerging Asian mining hubs where greenfield beneficiation plants are still being built rather than just maintained.

    Within our 1200 Mining stories, FLS appears frequently in service-centre and grinding-technology pieces, so winning a BHQ iron ore beneficiation order in south Asia likely reflects customers’ preference for integrated flowsheet and lifecycle support rather than stand‑alone equipment buys.

    Banded haematite quartzite (BHQ) iron ore typically requires fine grinding and complex separation; FLS’s concurrent work on vertical media regrind mills in other coverage suggests the company is positioning its comminution portfolio specifically for low‑grade, hard‑to‑liberate ores like these.

    Graphite One Alaska–Ohio supply chain: design and capex notes for mine planners

    Graphite One has secured a Conneaut, Ohio site from Bessemer and Lake Erie Railroad (CN subsidiary) for its Active Anode Materials facility, gaining direct Lake Erie port access, multi-line CN rail, an on-site substation and room to scale. The staged build-out targets an initial 25,000‑tonne module, ultimately 100,000 tonnes per year of anode material, supplied by the post‑feasibility Graphite Creek deposit in Alaska with a planned 20‑year mine life and backed by up to US$2 billion in potential EXIM funding. A separate Ohio finishing and blending plant aims for Q4 2027 completion with 10,000 t/y initial capacity, split into 4,000 t energy storage, 3,000 t fast‑charging and 3,000 t high‑energy‑density graphite products for lithium‑ion batteries.

    Jeff Currie’s $10,000 gold call: cycle, capex and price risks for mine planners

    Gold may retreat from about $4,500/oz. towards $4,000/oz. as Jeffrey Currie, former Goldman Sachs commodities chief and now Abaxx Markets executive co-chairman, stays tactically short, citing forced central bank sales such as Turkey’s roughly 120 tonnes of disposals to fund higher energy costs. Currie still targets a long-term move towards $10,000/oz., arguing that once central banks turn dovish after an energy-driven growth shock, the trade “resets”. He links this to a broader commodity super cycle driven by capex starvation and an estimated $820 billion of 2026 spending by the “Magnificent 7 plus Oracle”.

    Nouveau Monde Graphite Matawinie mine: project and supply-chain notes for engineers

    Construction has begun on Nouveau Monde Graphite’s C$2 billion Matawinie mine in Québec, fast-tracked through Canada’s Major Projects Office and designed to produce up to 106,000 tonnes of graphite per year, which would make it the largest graphite mine in the G7. Ottawa has backed the project with financing from Export Development Canada, the Canada Infrastructure Bank and the Canada Growth Fund, plus a seven-year offtake for 30,000 tonnes of concentrate annually. The mine, 120 km north of Montreal, is expected to create over 1,000 jobs and anchor an integrated graphite-to-battery materials chain with NMG’s planned Bécancour plant.
