The aims of this project address the critical mineral resource potential of complex copper ores. The research will generate new knowledge on the concentration, distribution, physical form and chemical speciation of critical minerals, including tellurium, cobalt and rare earth elements, in ores and processing streams using innovative approaches and utilising state-of-the-art analytical techniques. Expected outcomes include integrated models for critical element endowments in Australia's largest copper resource, Olympic Dam (S.A.). Future recovery of these elements would add significant value to existing operations, providing long-term economic and commercial benefits and would also contribute to Australia's transition to a low-carbon future.Read moreRead less

This proposal aims to systematically investigate the role of trace elements in controlling the kinetics, product composition, and feed-back between fluid flow and the reaction interface, in fluid-driven mineral reactions. This project expects to provide a framework for the integration of activator trace elements in models of crustal fluid flow and their application in the recovery of base, precious, and critical metals, using interdisciplinary approaches across geochemistry, mineral engineering and material sciences.

Carbon-neutral copper: unlocking metal value through carbon sequestration. This project aims to explore how the concepts of reaction-induced porosity and coupled dissolution-reprecipitation reactions, which have had a profound impact in geosciences, can be exploited in the context of ore processing through carbon sequestration. The project's main outcomes are to generate a new process that maintains porosity in ore, and a combination of lixiviants, for effective Cu metal recovery and Fe capture. ....Carbon-neutral copper: unlocking metal value through carbon sequestration. This project aims to explore how the concepts of reaction-induced porosity and coupled dissolution-reprecipitation reactions, which have had a profound impact in geosciences, can be exploited in the context of ore processing through carbon sequestration. The project's main outcomes are to generate a new process that maintains porosity in ore, and a combination of lixiviants, for effective Cu metal recovery and Fe capture. This project will benefit the mineral industry by providing an alternative to the current paradigm in Copper mineral processing that requires the destruction of the mineral hosting economic value, thereby developing sustainable mining technologies well suited for the increasingly complex ores being extracted in Australia.

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

Olympic Dam (OD) is a supergiant Cu-U-Au-Ag-REE ore deposit, containing more than a trillion Australian dollars worth of metals, and hosted by hematite-rich breccia in South Australia. Yet, key aspects of the geochemistry of OD-style deposits remain poorly understood. This project will conduct innovative experiments to address the role for fluorine in Fe, U and REE transport at OD, and the role of fluid-rock interaction in generating the unusually oxidised Fe-Cu mineral assemblages and in controlling U grades and distribution. The fundamental information gained will underpin intense on-going research aimed at discovering new OD-style orebodies and at creating new ore-processing technology that are environmentally sustainable and able to access lower-grade ores.Read moreRead less

This project aims to develop a new class of emulsion explosives, which are not susceptible to hot and reactive rock conditions in very deep-level ore mines. These emulsions will contain a tuneable polymer network to prevent collapsing of the emulsion columns in hot upholes in high temperature mines, along with additives to eliminate the exothermic reaction with the rocks. If not prevented the reaction can cause premature detonation or deflagration of the emulsion causing fatal injuries and generation of toxic NOx gases. Increase in economically and safely extractable deep-level ore volume that generates greater export earnings and more jobs are expected project outcomes, as is reduced atmospheric pollution.Read moreRead less

This project aims to investigate radical new approaches to reduce chemical and energy requirements for transformation of indigenous natural graphite to a high-value material graphene. The graphite which will be used is the by-product of the Uley mines of South Australia. Graphene is an atomically thin arrangement of carbon atoms with combinations of remarkable chemical inertness, strength, and massive surface area. Utilising fluid phase dispersed graphene, this project aims to develop scalable and industrially-adaptable methods to manufacture thin yet mechanically robust, inert, fouling-resistant, highly-permeable graphene-based asymmetric membranes. These advanced membranes are expected to find wide application in reducing discharge of mining effluents and recovery of precious metals.Read moreRead less
