The geochemistry of rare earth elements in carbonate melts. This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas. The global supply of these critical metals is geopolitically unstable and, although Australia has significant reserves, there is very limited production. By improving our understanding of the geochemical behaviour of the rare earths th ....The geochemistry of rare earth elements in carbonate melts. This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas. The global supply of these critical metals is geopolitically unstable and, although Australia has significant reserves, there is very limited production. By improving our understanding of the geochemical behaviour of the rare earths this project aims to develop new reverse-engineering methods for their extraction, which will improve the security of supply of these elements and enhance Australia's role in high-tech industries. The project will enhance the profitability of the Australian resources sector through improved extraction economics and will secure the supply of these critical metals for Australian high-tech industries and export. The outcomes will be targeted initially at junior resource companies that are not yet profitable.Read moreRead less

A Fundamental Study of the Breakage of Gibbsite and Smelter Grade Alumina. This project aims to develop a fundamental understanding of the cracking of gibbsite and smelter grade alumina, thus providing useful guidance for the alumina refineries to control the particle size distribution of the smelter grade alumina. This addresses an important issue in alumina refineries in terms of providing a high quality product for the downstream aluminium smelter.
Hydraulic erosion of granular structures: experiments and computational simulations. Erosion due to hydraulic forces causes vast damage to infrastructure and buildings in Australia and overseas. The project aims to improve the predictability and controllability of flooding related disasters caused by erosion. The project involves experiments as well as cutting edge computer simulations.

Adaptive Electrical Capacitance Volume Tomography for Multiphase Flows. This project aims to establish a cutting edge adaptive electrical capacitance volume tomography facility for real-time metering / imaging of multi-phase flows. Optimisation of these flows which are encountered in many industries, is paramount in today's carbon-constrained global economy. This project expects to generate the new knowledge necessary for such optimisations.

This project aims to establish a cutting edge adaptive electrical capacitance volume tomography facility for real-time metering / imaging of multi-phase flows. Optimisation of these flows which are encountered in many industries, is paramount in today's carbon-constrained global economy. This project expects to generate the new knowledge necessary for such optimisations. Expected outcomes include enhanced national capability for characterisation of multi-phase flows in real-time under both ambient and high temperatures. This should benefit and greatly facilitate the commercial rollout of novel technologies in industrial sectors as diverse as mineral processing, clean energy, fuels/chemicals, oil/gas, food and environmental remediation.

Engineered Inorganic Membranes for Novel Mineral Brine Processing. This project aims to synthesise a new generation of engineered hierarchical membranes for novel brine processing. The key concept of the research is the precise tailoring of pores of inorganic films, forming functional meso-structures for separating salts from water.

This project aims to synthesise a new generation of engineered hierarchical membranes for novel brine processing. The key concept of the research is the precise tailoring of pores of inorganic films, forming functional meso-structures for separating salts from water. Salt crystallises perpendicular to the surface of the membrane, whilst easily removed by air, a process that can be repeated many times leading to high production rates. The hierarchical membranes will be studied to elucidate the relationships between structure, composition, surface properties and transport phenomena. The outcomes should advance brine processing separation technologies for the mineral industry (lithium, potassium, and magnesium).Read moreRead less
Fundamental investigation of the briquetting behaviour of iron ore fines. Handling, including transport and processing, may account for up to 60 per cent of the total delivered price of iron ore. This project will develop an integrated computer model for an improved briquetting process of ore fines with reduced operation cost and less environmental impact, leading to a more competitive and sustainable mineral industry in Australia.
