The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an ....A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an order of magnitude by dramatically increasing bubble-liquid segregation rates, and bubble-surface fluxes. In turn the project is expected to develop a new line of solutions to industrial problems in hydrometallurgy for recovering precious metals and for solving toxic environmental problems.Read moreRead less
The Mineral factor: strategic minerals, imperial resources and global politics (1895-1995). With the emergence of Asia, the political control of 'rare earths' vital to high-tech industries has prompted international diplomatic and commercial concern. This project explores the history of 'strategic minerals' and assesses the role of minerals policy in achieving both 'mineral security' and environmental sustainability.
A unified model for the closure dynamics of ancient Tethys constrained by geodesy, structural geology, argon geochronology and tectonic reconstruction. The project will elucidate complex planetary dynamics involved in the interaction of the oceanic plates with the continental crust. Such aspects underpin the ability of geoscientists to effectively simulate and model, impacting on issues ranging from forecasting earthquakes to how to conduct greenfields exploration for energy and mineral resource ....A unified model for the closure dynamics of ancient Tethys constrained by geodesy, structural geology, argon geochronology and tectonic reconstruction.

Strength and resistance along oceanic megathrust faults: implications for subduction initiation. Hjorta Trench, south of Macquarie Island, is a seismically active boundary of the Australian plate and a unique natural laboratory for study of the initiation of the processes which are currently driving Australia north at 7 millimetres per year. Sophisticated computer models will be used to understand the evolution of this oceanic megathrust system.
Variational multiscale modelling of granular materials. Granular materials play an important role in a wide-range of problems related to physical infrastructure. These include landslides and similar catastrophic events often leading to loss of life and property. This project will aim to develop new methods for adequate simulation of granular flows to allow formulation of efficient risk mitigation strategies.
Critical metals from complex copper ores. 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 e ....Critical metals from complex copper ores. 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
Origin of silicic magmas in a primitive island arc: the first integrated experimental and short-lived isotope study of the Tongan-Kermadec system. The Tongan arc forms a large portion of the Australian plate boundary and is one of the most chemically primitive systems known. Oddly, it produces volumes of more evolved, dangerous silicic magmas. The results of this project will establish the source of these magmas and rates of migration, which are fundamental for understanding volcanic hazards.
Submarine volcanoes: degassing of silicic magma with implications for ascent and eruption processes. This research project will advance the basic understanding of how magma ascends and erupts in submarine settings. This study will identify the relative roles and timing of volcanic gas release from silicic magmas, using cutting-edge techniques newly available at the Australian Synchrotron.
Diamonds – Time Capsules of Ancient Mantle Volatiles and the Key to Dynamic Earth Evolution. This project aims to reconcile the radically different views on the structure of the Earth’s mantle, based on geochemical (mostly noble gas) and geophysical data. This objective will be addressed through innovative noble gas analyses of well-characterised diamond samples, including gem-stones used for previous dating studies. In combination with carbon isotopic results, this information will be used to c ....Diamonds – Time Capsules of Ancient Mantle Volatiles and the Key to Dynamic Earth Evolution. This project aims to reconcile the radically different views on the structure of the Earth’s mantle, based on geochemical (mostly noble gas) and geophysical data. This objective will be addressed through innovative noble gas analyses of well-characterised diamond samples, including gem-stones used for previous dating studies. In combination with carbon isotopic results, this information will be used to constrain the structure and temporal/spatial evolution of the Earth’s mantle. A related outcome will be an improved understanding of the mantle source regions of diamonds and diamond formation.Read moreRead less
Molecular scale engineering of solid/ionic liquid interfaces. Ionic liquids have enormous potential as advanced materials due to their unusual properties. This project will develop ways to use ionic liquids as lubricants, in electrochemical devices like capacitors, and in the electro-refining of metals. The technologies developed will decrease Australia's energy consumption and stimulate economic growth.
