Ehanced Hydrodynamic Fractionation of Particles. 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 ....Ehanced Hydrodynamic Fractionation of Particles. 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
Optimizing tailings dewatering through interfacial chemistry and particle interactions. This project aims to improve the dewatering behaviour of waste tailings from mineral processing activites. Dewatering and disposal of tailings containing fine particles are serious issues which confront the mineral industry. Effective dewatering of tailings is determined by particle-solution interfacial chemistry and particle interactions. These properties will be manipulated by matching the molecular arch ....Optimizing tailings dewatering through interfacial chemistry and particle interactions. This project aims to improve the dewatering behaviour of waste tailings from mineral processing activites. Dewatering and disposal of tailings containing fine particles are serious issues which confront the mineral industry. Effective dewatering of tailings is determined by particle-solution interfacial chemistry and particle interactions. These properties will be manipulated by matching the molecular architecture and functionality of flocculants to mineral particle surface chemistry. Optimization of tails interfacial chemistry and particle interactions through conventional and non-conventional flocculants will be investigated and electoosmosis will be applied to achieve maximum dewatering behaviour.The scientific and environmental outcomes will be beneficial to all stakeholders.Read moreRead less
Control Of Aggregate Structure, Settling And Dewatering In Mineral Tailings Processing. Modification of aggregate structures in mineral processing will lead to improved dewatering in tailings operations. In mine site rehabilitation and tailings utilisation, technology developed in this project may save not only millions of dollars in more efficient processing and tailing deposition but also help to better reuse our limited national water resources.
Particle Transport and Separation in High Aspect Ratio Inclined Channels. This project will be of benefit to the Australian coal and mineral processing industries, worth tens of billions of dollars to the Australian economy each year. The objective is to establish new options for the processing of particles as large as 50mm, and smaller than 50 microns in size, and hence significantly extend the operating size range of the Reflux Classifier. The development of new resources, especially those of ....Particle Transport and Separation in High Aspect Ratio Inclined Channels. This project will be of benefit to the Australian coal and mineral processing industries, worth tens of billions of dollars to the Australian economy each year. The objective is to establish new options for the processing of particles as large as 50mm, and smaller than 50 microns in size, and hence significantly extend the operating size range of the Reflux Classifier. The development of new resources, especially those of poorer grade, requires more effective separation technology. Success in this project will significantly benefit the end users of the technology and also contribute to Australia's Mining Services industry.Read moreRead less

The research conducted within AMSRI will enable our existing resource-based industries to be transformed through the application of new technologies, helping to create an environmentally sustainable nation, a key national research priority. The research programs in energy efficient liberation, frugal water use and waste management, innovative processing, material and interface science, advanced analysis and mathematics in minerals processing are of critical importance to Australia's major export industry. AMSRI will produce unique graduate students, educated in a multi-university, industry-linked research environment, who will provide a strong intellectual resource to both Australian industry and research institutions.Read moreRead less
Managing Contaminant Metals in Complex Hydrometallurgical Processes; Meeting techno-economic, environmental and operability objectives. Sustainability of the minerals industry is predicated on being able to refine metals from increasingly lower-grade ores. This brings with it the critical problem of managing all contaminant elements present to ensure overall economic and environmental performance. Hydrometallurgical processes are favoured, though difficulties arise in controlling product charact ....Managing Contaminant Metals in Complex Hydrometallurgical Processes; Meeting techno-economic, environmental and operability objectives. Sustainability of the minerals industry is predicated on being able to refine metals from increasingly lower-grade ores. This brings with it the critical problem of managing all contaminant elements present to ensure overall economic and environmental performance. Hydrometallurgical processes are favoured, though difficulties arise in controlling product character to suit downstream processing. This project will develop a fundamental understanding of precipitation processes for optimal recovery of contaminant elements (for a novel zinc process case study), considering the quantitative relationship between all major physico-chemical and engineering features. This will lead to enhanced process designs to meet techno-economic, environmental and operability objectivesRead moreRead less

Used in the paint, plastic, ceramic, paper and synthetic fibre industries and having strategic nano-technological applications, titania is an important commodity for Australia, earning about $1.3 billion p.a. in exports. Better production methods through improved understanding of titania precipitation chemistry will help to increase our industrial productivity and minimise energy consumption. It may also lead to useful new processes and/or materials with catalytic properties. In an increasingly competitive global market, this is most relevant to Australian titania exporters and to Australian renewable energy programs (particularly for generating photovoltaic power).

BIOPROSPECTING FOR NOVEL EXTRACTANTS TO SEPARATE NICKEL AND COBALT. Cobalt (Co) is a common 'guest' element in nickel (Ni) ore. Separating these metals is crucial to the production of high purity of Ni and Co, valuable metals for the Australian economy. Currently, processing of Ni-ore relies on energy-intensive dissolution followed by separation of Co from Ni using expensive synthetic chelators. A few rare Ni- and Co-accumulating plants however, have evolved biochemical mechanisms to distingu ....BIOPROSPECTING FOR NOVEL EXTRACTANTS TO SEPARATE NICKEL AND COBALT. Cobalt (Co) is a common 'guest' element in nickel (Ni) ore. Separating these metals is crucial to the production of high purity of Ni and Co, valuable metals for the Australian economy. Currently, processing of Ni-ore relies on energy-intensive dissolution followed by separation of Co from Ni using expensive synthetic chelators. A few rare Ni- and Co-accumulating plants however, have evolved biochemical mechanisms to distinguish between Ni and Co. We propose the first determination of the mechanisms of Ni/Co discrimination in these unusual plants, effectively biosprospecting for novel commercial extractants to separate Ni and Co.
