NEUTRALISING MINERAL REACTIONS IN ACID MINE DRAINAGE CONTROL. The project addresses the serious environmental problem of acid and toxic element release from iron sulfides in waste rock dumps and tailings storage in the mining industry. Long-term neutralising capacity, currently not tested in laboratory assessments, is available from the reaction of some silicate and aluminosilicate minerals. This potential has not been systematically tested or modelled. The research project aims to understand th ....NEUTRALISING MINERAL REACTIONS IN ACID MINE DRAINAGE CONTROL. The project addresses the serious environmental problem of acid and toxic element release from iron sulfides in waste rock dumps and tailings storage in the mining industry. Long-term neutralising capacity, currently not tested in laboratory assessments, is available from the reaction of some silicate and aluminosilicate minerals. This potential has not been systematically tested or modelled. The research project aims to understand the relative mechanisms and rates for long-term alleviation of acid production with mineral layered and blended combinations. Improved understanding will provide methodology for assessment and control of acid mine drainage.Read moreRead less

Origins and distributions of intraplate earthquakes. This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to im ....Origins and distributions of intraplate earthquakes. This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to improve models of future seismic hazard in Australia and globally. This will lead to improved predictions of future earthquake impacts in urban and natural environments and development of new paleoseismic techniques.Read moreRead less

Rethinking Australian drought risk, its long-term variability and processes. Drought risk describes the likelihood that damage will result from exposure to drought. This project aims to fundamentally reshape how we define, characterise and understand drought risk in Australia. A framework for drought risk will be applied that includes the complete range of characteristics that modulate the impacts of drought, which are the frequency of recurrence, duration, severity, seasonality and spatial exte ....Rethinking Australian drought risk, its long-term variability and processes. Drought risk describes the likelihood that damage will result from exposure to drought. This project aims to fundamentally reshape how we define, characterise and understand drought risk in Australia. A framework for drought risk will be applied that includes the complete range of characteristics that modulate the impacts of drought, which are the frequency of recurrence, duration, severity, seasonality and spatial extent. Long-term changes in drought risk will be examined and the process-based climatic risk factors will be identified. Advancing knowledge on the nature and causes of the long-term changes in drought risk is crucial to improving risk management of drought in the agricultural and water resource sectors.Read moreRead less
Environmentally Benign Flotation Chemicals. The research described in this proposal and the anticipated outcomes are concerned with replacing toxic and environmentally hazardous chemicals used in the mineral processing industry with benign chemicals that are biodegradable and have low toxicity. Replacing these chemicals reduces the risk of workplace injuries and damage to the environment that could be caused by industrial accidents.
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

Optimising the Recovery of Fine and Coarse Particles in Mineral Flotation. The collection of fine (<10 microns) and coarse (>100 microns) mineral particles by gas bubbles is the very heart of the selective froth flotation process. In the flotation of minerals, losses of fine and coarse value minerals equate to approximately $500M annually in Australia alone. The significance of flotation to the Australian economy may be judged from the fact that over $39b in commodity exports was derived from t ....Optimising the Recovery of Fine and Coarse Particles in Mineral Flotation. The collection of fine (<10 microns) and coarse (>100 microns) mineral particles by gas bubbles is the very heart of the selective froth flotation process. In the flotation of minerals, losses of fine and coarse value minerals equate to approximately $500M annually in Australia alone. The significance of flotation to the Australian economy may be judged from the fact that over $39b in commodity exports was derived from the minerals and energy industries in 2001, rising to well over $75b in 2005 (Australian Bureau of Statistics). These industries produce mineral concentrates of specific interest to our Industry Partner, such as copper, nickel, zinc and coal.Read moreRead less

Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality. This project aims to link fluvial disturbance with the capacity for effective riparian restoration in subtropical river systems at a local, reach and whole of catchment scale. The outcome aims to develop decision-support tools and methods for industry partners to invest in catchment-scale restoration activities in order to manage the risks to drinking water quality and aquatic ecosystem health from riverbank erosion.Read moreRead less
