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
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. 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 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
Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. Thi ....Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. This information will be input to comminution and wear models to predict pulveriser performance and wear patterns. Simulation results will be validated using measurements from scale visualisation and working models.Read moreRead less
New approaches to the treatment of potable water in the presence of algal blooms. The processing of blue green algae rich waters and subsequent release of algal metabolites causes taste and odour problems and toxins that affect potable water safety. This project will define a preferred approach to the processing of these waters and provide quantitative analysis tools to help water authorities guarantee water quality and safety. The defined process routes and analysis procedures will also resul ....New approaches to the treatment of potable water in the presence of algal blooms. The processing of blue green algae rich waters and subsequent release of algal metabolites causes taste and odour problems and toxins that affect potable water safety. This project will define a preferred approach to the processing of these waters and provide quantitative analysis tools to help water authorities guarantee water quality and safety. The defined process routes and analysis procedures will also result in better water conservation (lower net water losses in processing). This will allow better regulation of water quality, safety and management by water authorities and improve consumer confidence in the potable water supply.Read moreRead less
Production of Concentrated Fresh Milk Products. This project focuses on developing production processes for concentrated fresh milk ingredients for the international market. Ultrafiltration of whole milk solutions will be extended to maximise the product protein concentration. Electrodialysis and nanofiltration will be tailored to separate salts from lactose and produce 'designer' products with minimum wastage and energy consumption.

This project focuses on developing production processes for concentrated fresh milk ingredients for the international market. Ultrafiltration of whole milk solutions will be extended to maximise the product protein concentration. Electrodialysis and nanofiltration will be tailored to separate salts from lactose and produce 'designer' products with minimum wastage and energy consumption. Production of lactitol from dairy lactose, a potential new manufacturing operation for Australia, will be assessed. This project will result in diversion of quality ingredients from commodity markets to products with significant added value. The Korumburra region will benefit financially and socially from expansion in the local dairy industry.

Water resource is limited and has been continuously decreasing. The idea of recycling and reusing of wastewater has been adopted for irrigation, industry and other non-potable uses. In Australia, wastewater reuse is now considered a key strategy for conserving water at national, state and local level. In this study, the proposed treatment unit is to produce a superior effluent quality for water reuse while minimize membrane fouling of the membrane filtration system. Hence, it will benefit water industries globally and communities in Australia. There will be a major export opportunity from Australia to supply efficient, low-cost and sustainable flocculant together with an improved treatment system worldwide.Read moreRead less
