This project is concerned with new processes for the treatment of fine coal which forms an export market in excess of A$2 billion a year. The aim is to improve the separation of fine coal from silt and clay, and especially the recovery of larger particles in the flotation process. Further aims are to increase the ease of filtration and dewatering of fine coal, and to reduce the dust that is generated when fine coal is handled during transportation on land and sea. A laboratory-scale process will be developed and tested at a larger scale. The new knowledge that is gained will be essential for the successful introduction of the new technology into the Australian coal industry.Read moreRead less

This project aims to develop new, powerful and sophisticated, computer-based models that can reliably predict the results of chemical reactions in complex, high temperature metal production processes. This project expects to use these models, initially applied to copper smelting systems, to enable the improved recycling of other valuable metals. These models should be able to be applied to a wide range of technologies used in the metallurgical industry as most of the world’s metals are produced by these pyrometallurgical processes. This should provide significant benefits such as substantial improvements in productivity and process efficiencies, whilst at the same time delivering energy savings and improved use of valuable metal resources.Read moreRead less
Creating wealth from new resources - High temperature extraction of metals from complex copper ores and recycled materials. Most of the world’s copper is produced using high temperature chemical processing (smelting).

Most of the world’s copper is produced using high temperature chemical processing (smelting). Both primary ores and recycled raw materials contain valuable elements and also potentially harmful impurity elements. To unlock and utilise current and new resources, and also minimise the environmental impacts the industry has identified the need for new fundamental scientific data that describe the chemical behaviour of impurity elements in these systems. The project aims to then use the data to develop powerful computer-based thermodynamic models that can predict the products of complex industrial processes. These sophisticated tools are intended to then be used to improve the performance of existing industrial operations and assist in the development of new process designs.Read moreRead less

A new methodology for the measurement of transition metals ions in complex, high temperature oxide systems relevant to non-ferrous metal production. 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 Queensla ....A new methodology for the measurement of transition metals ions in complex, high temperature oxide systems relevant to non-ferrous metal production. 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
Improvements in the pyrometallurgical processing of nickel oxide and laterite ores at QNI Yabulu, North Queensland. The QNI Yabulu operation in Queensland is an important supplier of nickel and cobalt metals to the export market. The company is planning to expand the scale of the operations but is faced with two important sustainability issues.

The QNI Yabulu operation in Queensland is an important supplier of nickel and cobalt metals to the export market. The company is planning to expand the scale of the operations but is faced with two important sustainability issues. One is the recent changes to the European regulations that require very low levels of residual nickel oxide in the nickel metal product. The second issue relates to ensuring the supply and improved recovery of nickel and cobalt from oxide-based ores. Further fundamental scientific information is required to provide improved understanding of the complex chemical reactions occurring during the high temperature treatment of these materials, and to guide improvements in product quality, recovery and process efficiencyRead moreRead less
