    UQ coarse particle processing program: design and retrofit insights for mine engineers

    UQ coarse particle processing program: design and retrofit insights for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    The University of Queensland’s Collaborative Consortium for Coarse Particle Processing Research is entering a second five‑year phase to scale up coarse particle flotation technologies that allow recovery of particles up to several millimetres, reducing grinding energy and water use. Phase I delivered the JKHFmini laboratory rig and plant trials with Eriez HydroFloat and FLSmidth REFLUX Flotation Cell units on copper and gold ores, targeting coarser grind sizes than conventional circuits. The renewed program will expand pilot‑scale testing and integrated circuit modelling, with direct implications for comminution circuit design, tailings management and brownfield plant retrofits.

    Technical Brief

    • Phase I built the JKHFmini rig to replicate HydroFloat and REFLUX Flotation Cell hydrodynamics at bench scale.
    • UQ’s Sustainable Minerals Institute coordinates the CPR Program with multiple mining company sponsors funding the five‑year phases.

    Our Take

    Within our 1177 Mining stories, Australia-based items tied to The University of Queensland and its Sustainable Minerals Institute tend to focus on step-change processing methods rather than incremental plant tweaks, signalling that JKHFmini-scale work is likely aimed at de-risking full-plant adoption for operating mines.

    A five‑year second phase for the CPR Program is unusually long compared with most research-tagged projects in our database, which suggests participating operators are targeting fundamental flowsheet changes (such as coarse particle rejection and energy-efficient grinding) rather than short-term optimisation trials.

    Research and Sustainability-tagged pieces linked to Australian processing labs often precede OEM commercialisation announcements by several years, so work around JKHFmini may give early clues about which coarse particle processing technologies will be ready for plant-scale deployment late this decade.

    Litus–UWin Nanotech critical minerals JV: flowsheet design notes for engineers

    Calgary-based Litus has signed a 25 May memorandum of understanding with Taiwan’s UWin Nanotech to jointly develop selective extraction, separation, recovery and purification flowsheets for cobalt, lithium, nickel and other elements from battery recycling and other secondary sources. The collaboration will combine Litus’ LiNC one-step direct lithium extraction platform for low- and high-concentration brines and its ReLiGN battery recycling process with UWin’s hydrometallurgical systems used in Apple-certified e‑waste and Li-ion recycling. Engineers should watch for integrated nanomaterial–hydromet circuits targeting both critical minerals and rare earth elements in circular supply chains.

    Gold price erases 2026 gains: cost-of-carry and project impacts for miners

    Gold fell as much as 3.5% to $4,315/oz, its lowest since March, erasing 2026 gains after a strong US May nonfarm payrolls print pushed Treasury yields and the dollar higher and lifted Fed rate hike odds. US gold futures dropped over 3.2% to $4,342/oz, with CME FedWatch now pricing about a 68% chance of a December hike versus roughly 50% pre-data. Since the Iran war began and the Strait of Hormuz closure drove energy prices up, bullion has slid nearly 18%, raising the cost of carry for non-yielding gold.

    Almonty Industries’ US$700m notes: funding Sangdong ramp-up explained for mine planners

    Tungsten producer Almonty Industries is issuing US$700 million of 2.25% senior convertible notes, convertible at US$27.40 per share with a capped call at US$41.36, to fund about US$543 million of working capital plus US$50 million of debt refinancing, causing an 18% share price drop to roughly US$17.20. The notes, offered to qualified institutional buyers and settling on 9 June 2026, include an option for a further US$100 million. Funding supports ramp-up at the Sangdong mine in South Korea, where a 640,000 t/y plant targets 2,300 t/y tungsten concentrate, with Phase 2 aiming for 1.2 Mt/y and 4,600 t/y output.
