This project aims to selectively extract base and precious metals from their ores in saline and non-saline environments, building upon a patented process utilising edible glycine under oxidising and mildly alkaline solutions. Extraction processes of metals from primary resources mostly use harsh, toxic and/or non-recyclable reagents. Exploratory research has already indicated the potential for easy metal recovery from their alkaline glycinate solutions and recycling of the lixiviant (glycine). Anticipated outcomes are a safe, non-toxic process for extracting metals from primary resources.Read moreRead less

This project aims to develop an innovative assessment of dioxin formation through analysis and speciation of its precursors (Cl and Cu). Iron ore sintering is the industrial process with the highest emissions of dioxins and furans to the environment in Australia, which are amongst the most toxic substances produced by man. The aim of this project is to conduct critical investigations required for control of dioxin emissions during iron ore sintering. The expected outcome of this project is the development of control mechanisms for the process conditions responsible for dioxin formation. This should provide significant benefits, such as assisting the Australian iron ore industry to address the environmental requirements of their international trade partners and sustain their iron ore exports.Read moreRead less
Avoiding catastrophic failure of cable bolts in underground mines. This work aims to identify the factors responsible for the emerging problem of catastrophic failure of high-load cable bolts in underground mines and develop strategies for resisting their failure. The work is of high importance since failure of cable bolts is now being reported in several mines across Australia and is expected to become a problem world-wide. The work is novel as it intends to be the very first study of catastrop ....Avoiding catastrophic failure of cable bolts in underground mines. This work aims to identify the factors responsible for the emerging problem of catastrophic failure of high-load cable bolts in underground mines and develop strategies for resisting their failure. The work is of high importance since failure of cable bolts is now being reported in several mines across Australia and is expected to become a problem world-wide. The work is novel as it intends to be the very first study of catastrophic cable bolt failure. The expected outcome is the development of economically viable solutions for avoiding catastrophic cable bolt failure. It is anticipated that the findings will also be relevant to the civil engineering sector.Read moreRead less
Behaviour of a cementing slurry in a full-scale mining stope. Any mining technique that allows improved extraction of ore from underground workings results in improved financial viability of the mining process concerned. Such improved extraction rates are being achieved by backfilling previously mined voids with cemented mine waste, which also improves stability of the underground workings. This research will further improve the financial viability of mines using this technique by reducing the a ....Behaviour of a cementing slurry in a full-scale mining stope. Any mining technique that allows improved extraction of ore from underground workings results in improved financial viability of the mining process concerned. Such improved extraction rates are being achieved by backfilling previously mined voids with cemented mine waste, which also improves stability of the underground workings. This research will further improve the financial viability of mines using this technique by reducing the amount of cement used, without compromising the safety of workers. In some otherwise marginal mines, these savings could be the difference between the mine staying open and being placed on care-and-maintenance, with the potential loss of jobs in mainly remote parts of the country.Read moreRead less
Advanced studies on the hydrometallurgy and electrochemistry of primary copper sulphide ores. The exploitation of low quality copper ores is hampered by our poor understanding of the fundamental chemistry involved. In this project, advanced techniques will be developed to understand the leaching of copper to a level of detail not obtained before. This will allow mining companies to extract copper with minimal environmental footprint.

This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and fractures. This project integrates innovation in geology, chemistry, and mineral engineering, and will deliver mineral-scale reaction models that will increase efficiency of in-situ mining and leaching technologies. Knowledge generated can be applied to improve mineral exploration, mining, and processing, contributing to unlocking billions of dollars’ worth of resources tied up in low grade, mineralogically complex ores.Read moreRead less
