Enhancing Direct Cu Recovery through Increased Gas Processing Understanding. This project aims to investigate mechanisms of copper loss during smelting and find new ways to reduce the loss. Smelting, which produces copper matte product and slag tailings, is an important step of the copper-making process from copper sulphides. The loss of copper to slag can be as high as 12 per cent.

This project aims to investigate mechanisms of copper loss during smelting and find new ways to reduce the loss. Smelting, which produces copper matte product and slag tailings, is an important step of the copper-making process from copper sulphides. The loss of copper to slag can be as high as 12 per cent. The project aims to create new knowledge about copper loss by matte droplets floated with gas bubbles generated by chemical reactions to the slag phase. The outcomes are intended to enable copper smelters to maximise direct copper recovery, reduce copper production costs and increase the productivity of the smelting process.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). Both primary ores and recycled raw materials contain valuable elements and also potentially harmful impurity elements.

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
From exploration to mining: new geological strategies for sustaining high levels of copper production from the Mount Isa district. Mineral production at the Mount Isa copper and Ernest Henry copper-gold mines is worth more than $ 1 billion per year and this has underpinned the northern Queensland economy for a number of years. These resources are being depleted at a high rate, and no significant new discoveries have been made in over a decade. This project will provide some of the tools to defin ....From exploration to mining: new geological strategies for sustaining high levels of copper production from the Mount Isa district. Mineral production at the Mount Isa copper and Ernest Henry copper-gold mines is worth more than $ 1 billion per year and this has underpinned the northern Queensland economy for a number of years. These resources are being depleted at a high rate, and no significant new discoveries have been made in over a decade. This project will provide some of the tools to define new resources for the next generation, ensuring the prosperity of the region and bolstering the Australian economy. The timing is critical given the long lead time between discovery and production (in the order of 5 to 10 years). If successful the research may have major financial impacts at local, regional and national scales. It may also improve mine safety.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

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. 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.

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.

Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to study how the upper mantle emerges as a thermo-mechanically distinct boundary layer, how this emergent structure relates to anisotropy in the upper mantle, and how it is affected by cross-scale effects controlling fault zone behaviour and crustal dynamics.Read moreRead less
