Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will appl ....Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.Read moreRead less
Stabilisation of Titania Pigment Slurries During Processing. This project aims to improve the stabilisation properties of titania pigment slurries during production. Current polyphosphate dispersants used by Tiwest are unstable under processing conditions. Tailored, robust dispersing reagents will therefore be investigated in order to provide improved stabilisation of pigments during processing. Enhanced understanding of the dispersing reagents interaction with the titania pigment surface and th ....Stabilisation of Titania Pigment Slurries During Processing. This project aims to improve the stabilisation properties of titania pigment slurries during production. Current polyphosphate dispersants used by Tiwest are unstable under processing conditions. Tailored, robust dispersing reagents will therefore be investigated in order to provide improved stabilisation of pigments during processing. Enhanced understanding of the dispersing reagents interaction with the titania pigment surface and the subsequent stability of the pigment will allow advances in processing and consequently improved final products. The potential growth in market share, by improved product performance, is in excess of $50M pa.Read moreRead less
Matching flotation concentrate composition to downstream processing in copper production at the Olympic Dam operations of BHP Billiton. This research is important for the Australian and South Australian economies. There are both large capital and operating costs benefits if a successful and robust mineral separation can be achieved. Being able to separate different copper sulphide minerals in copper concentrates will have global significance. In the particular case of Olympic Dam mine, the imp ....Matching flotation concentrate composition to downstream processing in copper production at the Olympic Dam operations of BHP Billiton. This research is important for the Australian and South Australian economies. There are both large capital and operating costs benefits if a successful and robust mineral separation can be achieved. Being able to separate different copper sulphide minerals in copper concentrates will have global significance. In the particular case of Olympic Dam mine, the impact of being able to separate the copper sulphide minerals at the mineral processing stage is a significant reduction in operating costs, which is a result of reduced ore handling, mining and smelting costs.Read moreRead less
Lab-on-a-chip mass spectrometry tools for testing illicit drugs. This project aims to develop fit-for-purpose mass spectrometry tools for roadside and workplace testing of illicit drugs. The technology will be based on nanostructured semiconductor chips that are surface-functionalised to enable molecular capture without extensive sample processing and subsequent detection by a novel combination of techniques. The technology is expected to be applicable to saliva, sweat and urine samples.
Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality con ....Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality control and management practices are implemented. In addition, a better understanding and control of water quality in recycled/saline process water may lead to improved flotation stability and performance, and reduced reagent consumption.Read moreRead less
Mechanisms controlling enteroendocrine hormone secretion in human duodenum. This project aims to gain a deeper understanding of nutrient sensing pathways present in enteroendocrine cells within the human intestine. These cells control digestive function, blood glucose levels and food intake and are thus critical to digestion. This project will endeavour to be the first to assess the biology of human enteroendocrine cells and will use innovative approaches to deeply assess function from the level ....Mechanisms controlling enteroendocrine hormone secretion in human duodenum.
