Ehanced Hydrodynamic Fractionation of Particles. The coal industry, which is a major contributor to the Australian economy, urgently needs a new washability method following its decision to abandon the existing laboratory standard. The existing method relies on the use of heavy organic liquids which are known to be toxic to human health. The 'water-based' approach proposed in this study overcomes the problem of risk to human health, thus benefiting Australian workers, the immediate industry, and ....Ehanced Hydrodynamic Fractionation of Particles. The coal industry, which is a major contributor to the Australian economy, urgently needs a new washability method following its decision to abandon the existing laboratory standard. The existing method relies on the use of heavy organic liquids which are known to be toxic to human health. The 'water-based' approach proposed in this study overcomes the problem of risk to human health, thus benefiting Australian workers, the immediate industry, and wider community. New separation technologies that could benefit the minerals industries and other key industries should follow. The project will also result in the education and training of two postgraduate students, and the advancement of two postdoctoral researchers in this area of industry. Read moreRead less
Hydrodynamic enhancement and transformation of flotation. The purpose of this project is to address emerging challenges in coal and mineral processing associated with the steep decline in the quality of mining assets and the long term resource demands of China and India. A major advance in flotation technology is expected, leading to the highest possible product grade at a given recovery.
Hydrophobic particle recovery using permeable hydrophobic media. This project aims to solve an intractable problem in froth flotation. Bubbles will be replaced by permeable, hydrophobic media, minimising the viscous hydrodynamic resistance that limits ultrafine particle recovery. The project expects to generate new knowledge relating the efficacy of the novel media to its underlying physical structure, composition, geometry, and interfacial structure. Expected outcomes include a framework for de ....Hydrophobic particle recovery using permeable hydrophobic media. This project aims to solve an intractable problem in froth flotation. Bubbles will be replaced by permeable, hydrophobic media, minimising the viscous hydrodynamic resistance that limits ultrafine particle recovery. The project expects to generate new knowledge relating the efficacy of the novel media to its underlying physical structure, composition, geometry, and interfacial structure. Expected outcomes include a framework for developing alternative, highly permeable, hydrophobic media, and new high performance separation technologies. This is expected to benefit large scale, low-cost, ultrafast processing of particulate suspensions in mineral processing and waste water treatment.Read moreRead less
Surface characteristics and hydrodynamics in detachment of coarse particles. Froth flotation is widely used for separating coal and minerals from the gangue. The largest particles that can be floated in the industry are 10 times smaller than the particles that can be floated under quiescent conditions. This project aims to better understand and quantify the detachment of large particles from the bubble surface. It aims to develop innovative modelling and experimental approaches to examine the ef ....Surface characteristics and hydrodynamics in detachment of coarse particles.

Use of Parallel Inclined Channels to Enhance Foam Drainage in Ion Flotation. This study is concerned with increasing the rates of foam drainage in flotation processes. The findings will have direct benefit in the field of ion flotation, and will be highly relevant to the flotation of high value minerals worth tens of billions of dollars annually. The Reflux Classifier, a device that employs the Boycott Effect to achieve a significant increase in the effective area of the vessel, will be used.

The Reflux Classifier, a device that employs the Boycott Effect to achieve a significant increase in the effective area of the vessel, will be used. This device has already attracted three national awards in the area of gravity concentration in mineral processing. The study is ideal for training new researchers, especially at the PhD level, given the importance of the field to Australia. Read moreRead less
A Framework for Understanding and Applying the Reflux Classifier in Fine Particle Beneficiation. The Reflux Classifier is a novel Australian technology that is re-defining what is possible in the field of gravity separation across the mining industry. This new research aims to focus on a critical gap in the knowledge, concerned with the powerful internal synergies that exist between the particle-fluid hydrodynamics of the lower fluidised bed and the upper system of inclined channels.

The Reflux Classifier is a novel Australian technology that is re-defining what is possible in the field of gravity separation across the mining industry. This new research aims to focus on a critical gap in the knowledge, concerned with the powerful internal synergies that exist between the particle-fluid hydrodynamics of the lower fluidised bed and the upper system of inclined channels. The technology has already delivered nearly $1 billion in economic benefit, solving previously intractable problems. Through an experimental and theoretical study a new framework for understanding and applying this technology in fine particle beneficiation across an increasingly diverse range of applications is intended to be established.Read moreRead less
Veteran Culture and the Military Memoirs of the Revolutionary and Napoleonic Wars. This project contributes to an understanding not only of veteran culture in early nineteenth-century France and Europe, but also of the ways in which veterans across western cultures assimilate, process and reconstruct memories of war. This necessarily will lead to a better understanding of role story-telling in the construction of national histories. In addition to offering new insights that will inform scholarsh ....Veteran Culture and the Military Memoirs of the Revolutionary and Napoleonic Wars. This project contributes to an understanding not only of veteran culture in early nineteenth-century France and Europe, but also of the ways in which veterans across western cultures assimilate, process and reconstruct memories of war. This necessarily will lead to a better understanding of role story-telling in the construction of national histories. In addition to offering new insights that will inform scholarship and teaching in the field history, it will also redress a significant gap in the international literature. The findings of this study thus assist in establishing Australian historical scholarship at the forefront of international research initiatives in memory, auto-biography and memoir writing.

Particle Transport and Separation in High Aspect Ratio Inclined Channels. This project will be of benefit to the Australian coal and mineral processing industries, worth tens of billions of dollars to the Australian economy each year. The objective is to establish new options for the processing of particles as large as 50mm, and smaller than 50 microns in size, and hence significantly extend the operating size range of the Reflux Classifier. The development of new resources, especially those of ....Particle Transport and Separation in High Aspect Ratio Inclined Channels. This project will be of benefit to the Australian coal and mineral processing industries, worth tens of billions of dollars to the Australian economy each year. The objective is to establish new options for the processing of particles as large as 50mm, and smaller than 50 microns in size, and hence significantly extend the operating size range of the Reflux Classifier. The development of new resources, especially those of poorer grade, requires more effective separation technology. Success in this project will significantly benefit the end users of the technology and also contribute to Australia's Mining Services industry.Read moreRead less
