#Gold is a hot #mineral & commodity, but it can be tricky to extract from ore 🧪
@coeminerals.bsky.social scientist A/Prof Boris Albijanic - @curtinuniversity.bsky.social Kalgoorlie - is researching new ways to recover gold and other minerals. Gain an insight into his work: tinyurl.com/593jkfkh
According to some, gold may on track to become Australia's second-largest export earner, but it can be very challenging to recover from ore. COEMinerals scientist, Associate Professor Boris Albijanic (pictured) who is based in COEMinerals' Curtin University node / Kalgoorlie campus (Western Australia) is working closely industry to research new ways to recover gold and other minerals.

#circulareconomy #recycling #minerals
As pictured: COEMinerals Chief Investigator Professor George Franks, and researchers Dr John Lu and Dr Wei Sung (Will) Ng are applying froth flotation methods to separate out graphite from metal oxides in ‘black mass’ (a mixture that is produced when lithium-ion batteries are ‘shredded’ in readiness for recycling). Researchers recently visited Envirostream Australia Pty Ltd - an Australian battery recycling company / a subsidiary of Livium Ltd - which recycles retired Lithium-ion batteries (sourced from cars, powerwalls, power tools and more). Researchers toured facilities and presented a research update: thank you to Mark Griffiths for hosting!

COEMinerals shared a game-changing scientific breakthrough in the recovery of critical and rare earth minerals and metals today. Led by Centre researcher Professor Chun-Xia Zhao (pictured alongside Dr Guangze (Daniel) Yang) from the University of Adelaide’s School of Chemical Engineering, the Centre's research team has applied learnings from multiple scientific disciplines to mimic how a cancer-targeting drug finds cancer cells – but in this case finding a one-in-a-billion peptide molecule targeting a given mineral or metal. This advancement has the potential to unlock the equivalent of a ‘DNA code’ for every mineral and metal on planet Earth and revolutionise mineral processing. It also heralds environmental benefits.

@coeminerals.bsky.social Director L/Prof Kevin Galvin is pictured with University of Melbourne members and novel technology: High Pressure Dewatering Rolls (HPDR) Mark-II, a new dewatering technology for mineral tailings

See latest research paper for insights: tinyurl.com/htedp6yu 🧪
Pictured: COEMinerals Centre Director Laureate Professor Kevin Galvin recently visited our University of Melbourne (UOM) node, spending time with members and learning more about a new technology under development - the 'HPDR Mk-II' The HPDR-II is a novel solid–liquid separation device designed to address the challenges of dewatering mineral tailings, particularly those with fine particles. A new research paper published this week overviews the design, proof of concept (phase 1) and safe and continuous steady state operation (phase 2) of the device: 'High pressure dewatering rolls Mark-II: A novel dewatering technology for mineral tailings': https://www.sciencedirect.com/science/article/pii/S0892687525003802?via%3Dihub "Kevin’s visit gave us the opportunity to show off the novel High Pressure Dewatering Rolls (HPDR) technology (pictured), which is a continuous clothless filter that combines vacuum, compression and shear dewatering mechanisms. The dewatering rolls have been demonstrated to achieve comparable or better moisture reduction and throughput per unit filter area to conventional filter presses," Centre Chief Investigator Prof. Stickland shared.
