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.

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 the tens of $M p.a.. Improvements in environmental and social quality of life in mining areas and towns will also result from improved treatment.Read moreRead less
Nickel iron sulphide mineralogy: the link between mineral transformations and microstructure and magnetic properties. This project is about measuring the rate at which minerals transform or react and how metal diffusion controls these reactions. Metal diffusion in sulphides is much more rapid that in silicates and is still very significant at low temperatures (< 300 C). In this project, we are trying to measure the rate at which the principal ore of nickel, pentlandite, transforms to violarite ....Nickel iron sulphide mineralogy: the link between mineral transformations and microstructure and magnetic properties. This project is about measuring the rate at which minerals transform or react and how metal diffusion controls these reactions. Metal diffusion in sulphides is much more rapid that in silicates and is still very significant at low temperatures (< 300 C). In this project, we are trying to measure the rate at which the principal ore of nickel, pentlandite, transforms to violarite, another important nickel rich sulphide that forms from it in the upper parts of ore bodies. The arrangement of the metal atoms in these minerals is sensitive to temperature, so it may be used as a geothermometer.Read moreRead less

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.

Improving Aqueous Processing and Control of Copper-Uranium Leach Tails Behaviour. The research will provide essential training and equip us with better understanding, appropriate scientific knowledge and diagnostic tools for establishing an effective U and Cu mineral leaching and subsequent treatment processes. Specifically, improved valuable mineral dissolution rate, greater pulp handleability, efficient particles washing and pulp dewatering technology for treating U-Cu metal containing pulps ....Improving Aqueous Processing and Control of Copper-Uranium Leach Tails Behaviour. The research will provide essential training and equip us with better understanding, appropriate scientific knowledge and diagnostic tools for establishing an effective U and Cu mineral leaching and subsequent treatment processes. Specifically, improved valuable mineral dissolution rate, greater pulp handleability, efficient particles washing and pulp dewatering technology for treating U-Cu metal containing pulps, significant increase in productivity and production with reductions in reagents and human risk, will emerge. These beneficial outcomes will increase profitability and competitiveness of BHP-Billiton and Australian mineral export. Read moreRead less
