An assessment of carbon dioxide storage capacity of water bearing sedimentary basins. Dealing with the problems caused by climate change and global warming is among the greatest challenges facing Australia today. One of the approaches being considered to minimise anthropogenic influence over climate is the geo-sequestration of carbon dioxide (CO2). The proposed project will lead to greater understanding of storage capacity of sedimentary basins and identification of optimum injection conditions ....An assessment of carbon dioxide storage capacity of water bearing sedimentary basins. Dealing with the problems caused by climate change and global warming is among the greatest challenges facing Australia today. One of the approaches being considered to minimise anthropogenic influence over climate is the geo-sequestration of carbon dioxide (CO2). The proposed project will lead to greater understanding of storage capacity of sedimentary basins and identification of optimum injection conditions for geo-sequestration in such aquifers, and any potential mechanisms that could lead to migration of CO2 from the source rock back to the atmosphere.This will contribute to national efforts to reduce global warming, safeguard the Australian economy, and allow continued electricity generation from coal-fired plants.Read moreRead less

The proposed project has the potential to bring national economic benefits through sustainable infrastructure and environment, commercial enterprise and community health and safety. Mining industry in Australia plays a major role for creating significant employment in regional Australia, coal-fired electricity generation, and export income which underpins the international competitiveness of the entire Australian economy. The proposed project will assist Australian mining industry in gaining a better understanding of the mechanics of failure of large open cut mines, an improved design approach for high steep slopes, and in developing a new set of guidelines which can be used to assess such a risk.

Mechanisms for Pyrite Oxidation Control in Acid Mine Drainage. The annual costs of acid rock drainage (ARD) management at operating sites in Australia are $120M p.a.; over 15 years, a total cost of $1.8 billion for the whole industry. There are limitations to the ability of existing systems to cope with high capacity ARD, to the long-term effectiveness of these systems and high potential costs/liability of remediation. The value of the project outcomes to industry and government will be in reduc ....Mechanisms for Pyrite Oxidation Control in Acid Mine Drainage. The annual costs of acid rock drainage (ARD) management at operating sites in Australia are $120M p.a.; over 15 years, a total cost of $1.8 billion for the whole industry. There are limitations to the ability of existing systems to cope with high capacity ARD, to the long-term effectiveness of these systems and high potential costs/liability of remediation. The value of the project outcomes to industry and government will be in reduction of ARD release, well-understood long-term outcomes, reduced cost of treatments and improved control. The scale of these savings is in the tens of $M p.a. but also in potential improvements in environment (acid and toxic metals in streams), health and social quality of life in mining areas and towns.Read moreRead less

Insights gained from this research will also minimize the environmental and occupational health impacts of various process emissions, making the industry more sustainable.Read moreRead less
The Application of Polymer Inclusion Membranes for the Removal of Thiocyanate and Cyanide from Gold Ore Processing Wastewaters. The recovery of gold at Stawell Gold Mine can be improved by using cyanide and thiocyanate free water in the milling process. The aim of this research is the development of a novel separation technology for the removal of these two ions from mine wastewater to allow it to be recycled.

The recovery of gold at Stawell Gold Mine can be improved by using cyanide and thiocyanate free water in the milling process. The aim of this research is the development of a novel separation technology for the removal of these two ions from mine wastewater to allow it to be recycled. Novel polymeric materials, known as polymer inclusion membranes (PIMs), which have never been used before in industrial separation, will be at the centre of this technology. In addition to increasing gold recovery, this technology is expected to reduce substantially the reliance of the Australian goldmining industry on fresh water. This research will also promote PIM based separation as a viable industrial separation technology, applicable in other areas.Read moreRead less

The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas. In response to the industry's attempts to reduce the environmental impact of its processes, this project will conduct basic strategic research into the interaction between mercury vapour and gold surfaces at the nano-level. Our principal aim is to develop mercury sensor technology suited to alumina refineries. This innovative technology will be a significant breakthrough in the control of mercury emissions and have many other applications.

However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must extend current theoretical understanding and establish an experimental capability, hitherto unavailable in Australia, for measuring heat capacities and densities of solutions to temperatures as high as 300 C.Read moreRead less

In the current energy market, non-traditional fuels like oil shale are becoming more economically important. Australia has >33 billion tonnes of oil shales resources with potential for >1800 million tonnes of recoverable oil. This potential multi-billion dollar industry depends upon development of an efficient technology leading to economical oil production and much cleaner organic liquid fuels. Retorting and combustion, which are core parts of oil shale conversion technology, would benefit from improved process conditions. This research proposal intends to investigate the in-situ complex oil shale thermal conversion reactions that occur during the retorting and combustion processes. Improved understanding of these complex reactions could lead to substantial economic and environmental improvements in oil shale processing.Read moreRead less
