A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems.

Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an order of magnitude by dramatically increasing bubble-liquid segregation rates, and bubble-surface fluxes. In turn the project is expected to develop a new line of solutions to industrial problems in hydrometallurgy for recovering precious metals and for solving toxic environmental problems.Read moreRead less
Variational multiscale modelling of granular materials. Granular materials play an important role in a wide-range of problems related to physical infrastructure. These include landslides and similar catastrophic events often leading to loss of life and property. This project will aim to develop new methods for adequate simulation of granular flows to allow formulation of efficient risk mitigation strategies.

The facility will be used by the collaborating universities to investigate adsorption and interface properties with great precision, and to develop new and improved technologies for coal and mineral processing, saline water utilisation, water desalination, energy production and environment protection. In particular, the project will investigate innovative ways of using ion-interface interactions in saline water for cleaning coal and recovering value minerals by flotation, and for improving dissolved air flotation used in water treatment and desalination to produce drinking water. The project will further investigate novel ways of capturing CO2, storing natural gases and hydrogen, and tailoring nutrient nano-crystals for foliar delivery.Read moreRead less
Non-destructive process for treatment of fluorinated greenhouse gases. This research pursues the development of an energy-efficient, non-destructive process for transforming fluorine-containing greenhouse gases (GHGs) into valuable and environmentally benign products. The process will benefit Australia, by reducing emission of GHGs and offers a new technology for treatment of the growing stockpiles of synthetic GHGs.

Summary
Heat flow in granular media under extreme loading conditions. Heat flow in granular media is critical in geoscience and engineering, from shear heating in earthquake faults to failures of granular heat exchangers. These problems involve complex conditions which this project will quantify in relation to the emerging phenomena of grain plasticity and melting and thermal pressurisation.
Advanced signal processing techniques to improve prognostic models for rolling element bearings. Novel signal processing techniques for predicting the development of faults in rolling element bearings will be developed and employed in a statistical prognostic model. This will greatly improve the economics of operation of many different machines, including helicopters and other aircraft, mining machinery, and wind turbines.
A novel quantitative risk assessment framework for fractured rock slopes. Rock slope instabilities present grave risks to life and to the serviceability of major Australian infrastructure such as mines, roads and railways, and to coastal recreation areas. This project aims at developing tools for the quantitative risk assessment of fractured rock slopes based on rigorous rock mechanics, numerical methods and probabilistic methods.

Rock slope instabilities present grave risks to life and to the serviceability of major Australian infrastructure such as mines, roads and railways, and to coastal recreation areas. This project aims at developing tools for the quantitative risk assessment of fractured rock slopes based on rigorous rock mechanics, numerical methods and probabilistic methods.
The research outcomes will improve our understanding of natural and engineering rock slopes, reduce the uncertainties in the prediction of the safety of infrastructures, and thus minimize the loss and damage. The research outcomes can also be used to maintain workplace safety in mining environments and avoid disruptions to production.

Enhanced carbon removal in secondary steel refining. The purpose of this project is to develop effective methodologies to increase the decarburisation rate in the vacuum degassing process which is used for the production of high value added steel products at BlueScope Steel. It is expected that the project outcomes will result in improved quality and productivity of the high value added steel products.
Phosphorous and iron recovery from steelmaking slag for effective recycling. This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling. Changing ore grades in Australia, especially increasing P content, are placing a substantial proportion of these ore products at a competitive disadvantage.

This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling. Changing ore grades in Australia, especially increasing P content, are placing a substantial proportion of these ore products at a competitive disadvantage. The project will use an integrated approach to demonstrate, experimentally and theoretically, how key properties of slags can be manipulated to enhance partitioning and couple this analysis with fluid dynamics to model the kinetics of the separation process. The expected outcomes of this research are to: first, provide possible solutions to address the increasing P content in Australian iron ores, which could place future ore products at a competitive disadvantage within the global iron ore market; and second, to identify treatment methods and practices which would promote higher recycling rates of steelmaking slag, significantly reducing the volume of material stockpiled or sent to landfill.Read moreRead less
