The coal industry, which is a major contributor to the Australian economy, urgently needs a new washability method following its decision to abandon the existing laboratory standard. The existing method relies on the use of heavy organic liquids which are known to be toxic to human health. The 'water-based' approach proposed in this study overcomes the problem of risk to human health, thus benefiting Australian workers, the immediate industry, and wider community. New separation technologies that could benefit the minerals industries and other key industries should follow. The project will also result in the education and training of two postgraduate students, and the advancement of two postdoctoral researchers in this area of industry. Read moreRead less
Application of Water Based Fractionation in the Assessment of Metallurgical Coal. The metallurgical coal market (13% of coal market) is highly specialized, and competitive. The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities.

The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities. A new water based fractionation method will be established, and a systematic investigation into the effects of the organic liquids will be undertaken. These results will be used to build a case for replacing the organic liquids used in the industry, which are known to have negative health and environmental impacts. 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.

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.

Flotation is an important process for upgrading low-grade ores to high-grade concentrates, and for recovering fine coal from tailings. This project is aimed at solving a long-term problem in current flotation practice, the difficulty in recovering ultrafine and coarse particles, currently lost from production. We will pursue two new discoveries recently made by us, relating to the recovery of ultrafines and coarse particles. Benefits to Australia are of the order of $500 million a year in increased exports, education of high-quality graduates, export income from license fees and equipment.Read moreRead less
