    Adelaide-developed crusher: energy and CO₂ implications for plant designers

    Adelaide-developed crusher: energy and CO₂ implications for plant designers

    First reported on Australian Mining

    30 Second Briefing

    A new low-emission crushing technology developed at the University of Adelaide aims to cut comminution energy use by targeting ore breakage at natural grain boundaries rather than by conventional compressive crushing. Led by researcher Mark Drechsler, the lab-scale unit is being tested on copper and gold ores to quantify reductions in specific energy consumption and downstream grinding requirements. If pilot-scale trials confirm lower kWh/t and improved liberation, plant designers could downsize SAG/ball mills and reduce both capital cost and CO₂ intensity of mineral processing circuits.

    Technical Brief

    • If proven, similar grain-boundary–targeted devices could be tailored to complex, fine-grained ore bodies.

    Our Take

    South Australia features in relatively few of our 1116 Mining stories compared with the eastern states, so an Adelaide University-driven processing technology could give local operations a niche in low-footprint plant design rather than just bulk commodity output.

    Within the 840 tag-matched pieces on Research/Sustainability/Product, most items focus on incremental plant retrofits rather than new crushing concepts, suggesting this work may appeal to brownfield Australian sites looking for step-change energy or media savings without full circuit redesign.

    Australian university-led mining innovations in our database tend to move into commercial trials via METS companies rather than miners themselves, so any scale-up of this Adelaide-developed crusher in Australia is likely to hinge on a local OEM or engineering firm taking the IP to market.

    From reactive to predictive mining safety: data and sensing priorities for engineers

    Mining safety specialist David Coghlan, head of technology and product at TURCK, argues that connected sensing and control must shift mines from reactive alarms to predictive intervention as fleets, conveyors and fixed plant become more automated. He points to integrated proximity detection, real-time location and condition monitoring on mobile equipment, tied into site-wide networks, as the basis for predicting collision and entrapment risks rather than just logging incidents. For geotechnical and operations teams, this means designing safety systems around data quality, latency and interoperability, not just compliance with existing guarding and lock-out procedures.

    Evolution becomes Carnaby’s largest shareholder: M&A and project signals for mine planners

    Evolution Mining has become Carnaby Resources’ largest shareholder with a 13.7 per cent stake after acquiring the QIC Queensland Critical Minerals Fund’s ~37.9 million Carnaby shares as part of its proposed $213 million takeover. Evolution also issued about 2.6 million new shares to QIC, signalling continued use of scrip-based structures in Australian mid-tier M&A. For copper–gold project developers, the move points to stronger strategic interest from established producers in advanced exploration portfolios rather than greenfield assets.

    Develop’s Woodlawn drilling: 15-year mine life implications for planners and geotechs

    Develop Global’s latest underground drilling at the Woodlawn copper–zinc mine in New South Wales has returned intercepts grading up to 15.7 per cent copper equivalent (CuEq), supporting its Project DM15 plan to extend mine life from 10 to 15 years. The high-grade results, from step-out holes targeting depth extensions of existing lenses, suggest additional sulphide resources beyond the current reserve envelope. For mine planners and geotechs, this points to a longer stoping schedule, potential redesign of sequencing and backfill, and extended use of existing underground infrastructure.
