Controlling arsenic to unlock value in gold and copper resources. This project aims to characterise the transformation of arsenic between oxidation states during mineral processing. Up to one third of the world’s gold reserves are locked up in arsenic rich minerals and 5000 tonnes of arsenic is released annually from mine waste. The project will enable the development of process technology that immobilises and removes arsenic at the earliest possible stage. The use of novel time-resolved in-situ ....Controlling arsenic to unlock value in gold and copper resources. This project aims to characterise the transformation of arsenic between oxidation states during mineral processing. Up to one third of the world’s gold reserves are locked up in arsenic rich minerals and 5000 tonnes of arsenic is released annually from mine waste. The project will enable the development of process technology that immobilises and removes arsenic at the earliest possible stage. The use of novel time-resolved in-situ techniques proposed in this research will give vital information of the complex chemical pathways involved during processing which current characterization methods on pre- and post-processed species do not achieve.Read moreRead less
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

Innovative Grid-Connected, Small-Scale Wind Turbine Generators Offering Low Cost and Wide Operating Speed Range. Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide. Grid-connected inverters are an efficient way of utilising small wind turbines on domestic, farming or small commercial properties which have access to the power grid.

Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide. Grid-connected inverters are an efficient way of utilising small wind turbines on domestic, farming or small commercial properties which have access to the power grid. Existing small-scale, grid-connected wind turbines are expensive and have a limited operating wind speed range. We are investigating new designs for low-cost wind turbine generators which can produce power over a wide range of wind speeds. The project should result in a greater application of small-scale wind generators in Australia and will lead to reductions in fossil fuel usage and greenhouse gas emissions.Read moreRead less

The project will directly benefit the Victorian power industry through water saving. If the new proposed hybrid cooling system concept is proved to be practically feasible, it will put the Australian power industry in a strong competitive position in terms of its efficiencies and waste heat recovery technology. Lowering the temperature of water into the cooling tower by 2 degree, by using the hybrid cooling system, it would save over 17,500,000 tons of makeup water per year for the Victorian power industry alone. At the same time, the waste heat recovered by the heat pump can be fed back to the power generation cycle. Read moreRead less
