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
Evaluation of reaction mechanisms and products in acid rock drainage treatments. There are more than 54 sites in Australia managing major ARD wastes (either >10% of the waste or >10M tonnes) with another 62 sites with less ARD. At operating sites, the annual costs are $60M p.a.; over 15 years, a total cost of $900M for the whole industry. The value of the project outcomes to industry (and government) in reduction of acid and toxic metal release and reduced cost of treatments is potentially in th ....Evaluation of reaction mechanisms and products in acid rock drainage treatments.

Summary
Nanoscale Interaction Forces in Particulate and Molecular Systems. We seek to establish a world-class facility for the measurement of nanoscale interaction forces. The ability to measure forces between particles, polymers, emulsion droplets, bubbles, proteins and powders will augment our research capabilities in minerals and material processing, thin film technology, structured surfaces, and in molecular and bio-technology (eg. proteins, DNA, cells, bone, bio-implants). A Molecular Force Probe ....Nanoscale Interaction Forces in Particulate and Molecular Systems. We seek to establish a world-class facility for the measurement of nanoscale interaction forces. The ability to measure forces between particles, polymers, emulsion droplets, bubbles, proteins and powders will augment our research capabilities in minerals and material processing, thin film technology, structured surfaces, and in molecular and bio-technology (eg. proteins, DNA, cells, bone, bio-implants). A Molecular Force Probe (Asylum Research) instrument will allow precise and flexible force measurements on the nano-metre scale. The proposed multi-disciplinary facility will advance research in the areas of engineering, chemistry, pharmacology and biotechnology.

Control Of Aggregate Structure, Settling And Dewatering In Mineral Tailings Processing. Modification of aggregate structures in mineral processing will lead to improved dewatering in tailings operations. In mine site rehabilitation and tailings utilisation, technology developed in this project may save not only millions of dollars in more efficient processing and tailing deposition but also help to better reuse our limited national water resources.
