Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions.

Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less
Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of g ....Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.Read moreRead less

Summary
A chemical looping process for carbon fibre production from plastics. This project aims to develop Mineral Looping Plastic Reforming (MLPR), a chemical looping reforming process for tonnage production of carbon nanofibers from plastic waste. This efficient process uses naturally occurring minerals (limestone, dolomite and ilmenite) to convert plastic waste to carbon nanofibers. The project will research the inner working of the MLPR process and the reforming reactions of plastics in the presence ....A chemical looping process for carbon fibre production from plastics.

This efficient process uses naturally occurring minerals (limestone, dolomite and ilmenite) to convert plastic waste to carbon nanofibers. The project will research the inner working of the MLPR process and the reforming reactions of plastics in the presence of naturally occurring mineral mixtures. This project is expected to make Australia a leader in waste use, facilitate the uptake of abundant waste streams to produce high value products, and resolve sustainability, energy and environmental issues in Australia.Read moreRead less

Many chemical reactions occurring in solid materials during heating significantly affect the materials' stability, and subsequently affects the processes of production of clean energy, material synthesis, catalyst preparation, and nanotechnology. No equipment currently exists in Australia that will mitigate the wide range of conditions in such reactions in materials processing. This situation impedes research progress in Australia, disadvantages Australian research students, and ultimately makes our research less competitive internationally. The establishment of the proposed apparatus will increase the competitiveness of Australian science and engineering, and contribute to the development of new Australian technologies that are important to the Australian economy and to environmental sustainability.Read moreRead less

This project aims to investigate the thermal decomposition of per- and poly-fluroalkyl substances (PFAS). The project will focus on the catalytic destruction of PFAS reactions at elevated temperatures, which is expected to transform PFAS in a controlled and predictable way into benign products. By understanding the fate of these compounds during thermal decomposition, the project will allow the development of a new technology aimed at treating materials which have been contaminated with or have been used as absorbants for PFAS. The project will provide the technical underpinning of a new technology developed to treat fluorochemical-contaminated material and, in doing so, reduce the environmental impact of these contaminants.Read moreRead less
Phosphorous and iron recovery from steelmaking slag for effective recycling. This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling.

This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling. Changing ore grades in Australia, especially increasing P content, are placing a substantial proportion of these ore products at a competitive disadvantage. The project will use an integrated approach to demonstrate, experimentally and theoretically, how key properties of slags can be manipulated to enhance partitioning and couple this analysis with fluid dynamics to model the kinetics of the separation process. The expected outcomes of this research are to: first, provide possible solutions to address the increasing P content in Australian iron ores, which could place future ore products at a competitive disadvantage within the global iron ore market; and second, to identify treatment methods and practices which would promote higher recycling rates of steelmaking slag, significantly reducing the volume of material stockpiled or sent to landfill.Read moreRead less

A variety of noble metal gallium alloy combinations will be investigated for their catalytic activities which are expected to show very high kinetics. We will study both bulk and low dimensional analogues to understand the atomic dispersion of noble metals on interface and in the core of the alloys, for discoveries regarding the liquid state catalytic properties of the mixes. Subsequently, model chemical reactions will reveal the enhancement of the kinetics and what the project can offer to industrial innovations. Read moreRead less
