The Network aims to develop long-term, collaborative research and training links between world-class researchers and research centres in mineral processing, extraction and refining. The goal is to ensure that Australia's major export industry is sustainable, environmentally acceptable and technically at the cutting edge.
Networking key researchers with complementary skills and expertise will enhance research quality, encourage a holistic approach to problem solving and support researchers to tackle big challenges, beyond their usual scope, that will transform the industry. The outcomes will be greater international competitiveness, better resource utilisation, and the incubation of new research leaders, enhancing Australia's minerals R&D infrastructure.Read moreRead less

The unique properties of nanomaterials have recently been fully realized, and their use has resulted in new technologies, transforming industrial processes. Our research teams at Griffith, Monash and Queensland University of Technology develop optimal, nanostructured materials for technological applications. To maintain a competitive edge in this research, we require a near excitation Raman spectrometer. Used in-situ, it rapidly yields structural information on the materials, enabling their formation and function to be better understood. This information will allow enhanced design and synthesis of nanomaterials, producing advanced products and processes for the energy, biotechnology, environmental and mining fields.Read moreRead less
Multiscale modelling of the transport phenomena of liquid iron and slag in ironmaking blast furnace. Blast furnace ironmaking is a key operation in the steel industry which, with an annual turnover around $11 billion, is a significant manufacturing sector in Australia. This project, focused on the behaviour of liquid iron and slag, can generate computer models that can reliably describe the complicated multiphase flow and thermochemical processes in the furnace.

Blast furnace ironmaking is a key operation in the steel industry which, with an annual turnover around $11 billion, is a significant manufacturing sector in Australia. This project, focused on the behaviour of liquid iron and slag, can generate computer models that can reliably describe the complicated multiphase flow and thermochemical processes in the furnace. The implementation of the resultant models and the new understanding should lead to long life campaigns, better operational control, decreased fuel consumption, improved productivity and reduced environmental impact. This, together with the proposed research training, is important to the development of Australia's competitive steel industry.Read moreRead less
Heat capacities of Bayer liquors to 300C. Alumina refining is one of Australia's most important industries, earning ~$6 billion per year export income. However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions.

However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must extend current theoretical understanding and establish an experimental capability, hitherto unavailable in Australia, for measuring heat capacities and densities of solutions to temperatures as high as 300 C.Read moreRead less
Development of an efficient oxygen-thiosulfate process for the recovery of gold from ores. Gold is currently recovered from the ore by a cyanide leaching process. This high risk procedure is used because there is currently no safe alternative. The research we propose to undertake will investigate a novel thiosulfate-oxygen process to dissolve gold. Successful completion of the project will identify the mechanism of the process and could lead to the replacement of the highly toxic cyanide with th ....Development of an efficient oxygen-thiosulfate process for the recovery of gold from ores. Gold is currently recovered from the ore by a cyanide leaching process. This high risk procedure is used because there is currently no safe alternative. The research we propose to undertake will investigate a novel thiosulfate-oxygen process to dissolve gold. Successful completion of the project will identify the mechanism of the process and could lead to the replacement of the highly toxic cyanide with the non toxic thiosulfate. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the use of cyanide.Read moreRead less
The effect of contaminant carbon films on the leaching of gold. A major problem in cyanidation is preg-robbing, which results in severe gold losses to tailings. Too much emphasis has been placed on the blinding and characterisation of free carbon or graphite particles, instead of considering carbon or graphite as a layer on top of other ore particles. It is the aim of this project to investigate the effect of contaminant carbon layers on the leaching of gold from sulphide ores. The understanding ....The effect of contaminant carbon films on the leaching of gold. A major problem in cyanidation is preg-robbing, which results in severe gold losses to tailings. Too much emphasis has been placed on the blinding and characterisation of free carbon or graphite particles, instead of considering carbon or graphite as a layer on top of other ore particles. It is the aim of this project to investigate the effect of contaminant carbon layers on the leaching of gold from sulphide ores. The understanding of the exact role of carbon layers on mineral surfaces in both preg-robbing and leaching is essential to devise process strategies that could lead to improved extraction.Read moreRead less

This proposal involves the application of three dimensional atom probe field ion microscopy and advanced transmission electron microscopy techniques to study the phenomena of precipitation and solute atoms' interactions with dislocations in warm rolled low carbon steels and interstitial free steels. It is intended to examine the effect of alloying additions on in-grain shear bands formation, texture formation and formability of warm rolled and annealed low carbon steels. Ultimately, the project is concerned with developing of fundamental understanging of solute interactions which provide an improved basis for design of these economically significant steels.Read moreRead less
Improving the Continuous Copper Converting Process Using Ferrous Calcium Silicate Slags. Replacement of refractories due to slag attack is a major cost in the copper making process. Metallurgists need to find a better slag which retains the benefits of current slags but is less aggressive towards refractories.
