ECOLOGICALLY SAFE RECYCLING OF ELECTRONIC SCRAP - CHEMICAL THERMODYNAMICS OF NOVEL HIGH TEMPERATURE PROCESSING TECHNOLOGY. As a developed industrialized society we are faced with increasing problems associated with the obsolete electronic materials.

As a developed industrialized society we are faced with increasing problems associated with the obsolete electronic materials. These materials are classed as hazardous wastes because they contain heavy metals and other elements that must be removed or made chemically inert before they can be disposed of safely. Electronic components however also represent a source of valuable elements that can be recovered and reused. The project will assist in finding safe, cost-efficient ways in which we can process these materials and, at the same time, recover the valuable metals contained within them. The project will thus contribute to the sustainable use of our raw materials and a cleaner environment.Read moreRead less

Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry.

Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may delineate adjacent plus regionally distributed zones where the deformation event responsible for mineralization is locally present at sufficient intensity to form ore. This would allow targeted deep drilling in ground with no ore close to the surface saving millions in drilling costs and dramatically increasing the financial viability of this industry.

Surface mechanical attrition treatment will be used to generate nanometer-sized grains in the surface layer of engineering magnesium alloys, and therefore activate the surface of this material. Together with the use of efficient activators, the project will develop a novel low temperature surface alloying technique to significantly improve the wear and corrosion resistance of magnesium alloys without changing the substrate properties. Microstructural features and the wear and corrosion resistance of the ultrafine-grained surface layer will be examined. In addition, it may be possible to combine the surface alloying process with the conventional ageing process together in order to save energy.Read moreRead less

Complex multi-component molten oxide phases, known commonly as slags, are used in the high temperature production and refining of metals. The slag systems of commercial interest contain transition metals species, such as, Fe2+, Fe3+. Each of these species behaves as if it were a separate chemical component. Researchers at the University of Queensland have developed a new methodolgy, which enables the concentrations of these transition metal ions to be measured.
These types of measurements cannot be made with any of the techniques currently in use. The study will provide data on high temperature slags in a number of industrially and scientifically important systems. This approach will be applicable to a wide range of chemical systems in the fields of extractive metallurgy, materials science and geology; systems which could not previously be characterised.Read moreRead less
