This project directly supports the solvent extraction industry in Australia. This industry is responsible for generating in excess of $600M annually of export earnings for Australia. This type of technology can be applied in the recovery of base metals such as coper, nickel, cobalt, etc and in the environmental area for the clean up of heavy metals from waste water. Solvent extraction has the advantage of high selectivity that enables metals to be recovered and recycled, thus reducing the wastage of these metals in, for example, the chromium plating process.Read moreRead less
The Role of the Interface in Solvent Extraction. This project involves a fundamental study of the kinetics of reactions that occur in solvent extraction processes used for separation of many of Australia's metals from minerals. The understanding gained from this will enable a greater efficiency to be obtained from Australia's minerals industry. In particular, it is intended to investigate the role of additives on the kinetics of metal extraction; these additives either enter the solution from ....The Role of the Interface in Solvent Extraction. This project involves a fundamental study of the kinetics of reactions that occur in solvent extraction processes used for separation of many of Australia's metals from minerals. The understanding gained from this will enable a greater efficiency to be obtained from Australia's minerals industry. In particular, it is intended to investigate the role of additives on the kinetics of metal extraction; these additives either enter the solution from the ore or are added as flocculants during the process, and have a significant effect on the performance. With the move to smaller, shorter residence time contactors, this has become increasingly important if these new contactors are to be used efficiently.Read moreRead less
Particle classification using a ferrofluid in a non uniform magnetic field. The separation of micron size components of suspensions according to the size and density of the particles is presently an intractable problem. However, by using a magnetized ferrofluid it should be possible to generate unique particle trajectories for each combination of particle size and density. This study investigates the potential of this strategy for separating such particles, laying the foundation for new small-sc ....Particle classification using a ferrofluid in a non uniform magnetic field.

However, by using a magnetized ferrofluid it should be possible to generate unique particle trajectories for each combination of particle size and density. This study investigates the potential of this strategy for separating such particles, laying the foundation for new small-scale diagnostic "lab-on a chip" technology that could be used in biotechnology to study whole blood, or in mineral processing to control energy intensive ball mills for mineral particle liberation.Read moreRead less
New understanding of turbulent flames with soot and particulate fuels. This project will develop the new understanding and models required to optimise practical furnaces, boilers and combustion chambers, most of which involve soot and/or particulate fuels. This work will be performed with state-of-the-art measurement and modelling tools through a well-established partnership of international researchers.
Fundamental research for advanced gasification technologies for low-rank coal and biomass in the carbon-constrained world. This project aims to acquire fundamental knowledge in order to develop advanced gasification technologies with high efficiencies and the capability to couple with carbon storage facilities in the carbon-constrained future. These technologies will contribute to the reduction of Australia's CO2 emissions using its cheap low-rank coal and biomass.
Synthesis of oligomers in dense carbon dioxide. The aim of the project is to develop a novel technique for the synthesis of low molecular weight polymers (oligomers) using dense carbon dioxide as a polymerisation solvent. The use of elevated pressure is the major impediment to the commercialisation of such technology. The technique proposed in this project will enable oligomers to be produced at greatly reduced operating pressures and may lead to a more general procedure for conducting other t ....Synthesis of oligomers in dense carbon dioxide.

Summary
A novel pyrolysis process for high-quality bio-oil production from biomass. The project outcome will provide fundamental knowledge essential to the development of a novel pyrolysis process for high-quality bio-oil production with biochar, a value-added by-product. It will largely accelerate the commercialisation of the biomass pyrolysis process to reduce greenhouse gas emissions and fossil fuel use in the energy sector.

The aim of this study is to develop a fundamental understanding of the influence of a set of parallel inclined plates within a liquid fluidized bed. A broad range of systems that process particulate suspensions are very likely to benefit from this innovative arrangement. Considerably higher throughputs and improved separation performance are expected. A theoretical model will be developed and validated experimentally. The study will also examine whether a critical shear rate can be used to selectively separate particles on the basis of differences in density. This work will strengthen the potential exploitation of this new technology, and help train and educate a student at the PhD level in the area.Read moreRead less
