Enhanced recovery and concentration of cenospheres from fly ash. The purpose of this project is to investigate the recovery of valuable particles, referred to as cenospheres, from the fly ash waste of coal fired power stations. An understanding of the complex gravitational settling behaviour of fly ash suspensions in inclined channels will lead to a new technology for recovering and concentrating the particles.
Long-term acid rock and tailings drainage mitigation through source control. Effective long-term management of acid rock drainage (ARD) from sulfidic mine wastes in current, exhausted and legacy mine sites is of critical importance to communities and for sustainable mining. An optimised geochemical and microbial multi-barrier approach to long-term reduction of ARD to environmentally acceptable rates will be developed by this project.
Improved control of dioxin emissions during iron ore sintering. This project aims to develop an innovative assessment of dioxin formation through analysis and speciation of its precursors (Cl and Cu). Iron ore sintering is the industrial process with the highest emissions of dioxins and furans to the environment in Australia, which are amongst the most toxic substances produced by man. The aim of this project is to conduct critical investigations required for control of dioxin emissions during i ....Improved control of dioxin emissions during iron ore sintering. This project aims to develop an innovative assessment of dioxin formation through analysis and speciation of its precursors (Cl and Cu). Iron ore sintering is the industrial process with the highest emissions of dioxins and furans to the environment in Australia, which are amongst the most toxic substances produced by man. The aim of this project is to conduct critical investigations required for control of dioxin emissions during iron ore sintering. The expected outcome of this project is the development of control mechanisms for the process conditions responsible for dioxin formation. This should provide significant benefits, such as assisting the Australian iron ore industry to address the environmental requirements of their international trade partners and sustain their iron ore exports.Read moreRead less
Numerical and experimental studies of the gas-particle flow and dust collection in electrostatic precipitation systems. This project will generate an integrated computer model to describe the gas-solid flow and dust collection in an ElectroStatic Precipitator (ESP). The model can be used to aid the design and control of ESP systems which are widely used for dust collection, leading to more competitive energy and related industries.
Hot stage separation of non-ferrous fraction during iron ore reduction. The project aims to provide in-situ investigation of the behaviour and properties of the non-ferrous fraction in iron ore during reduction. The results aim to allow industry to: improve the quality of the final metallic iron product; economically separate and recover high-value non-ferrous impurities in the iron ore; reduce waste generated by ironmaking; and enable utilisation of, and add value to, iron ores that currently a ....Hot stage separation of non-ferrous fraction during iron ore reduction. The project aims to provide in-situ investigation of the behaviour and properties of the non-ferrous fraction in iron ore during reduction. The results aim to allow industry to: improve the quality of the final metallic iron product; economically separate and recover high-value non-ferrous impurities in the iron ore; reduce waste generated by ironmaking; and enable utilisation of, and add value to, iron ores that currently are not commercially viable due to their high impurity levels and low iron contents. The project aims to help expand the mining potential of the currently unviable iron ore deposits and enable industry to maintain the economic benefits from iron ore production in the years to come.Read moreRead less
Atmospheric emissions of toxic trace metals and volatiles during thermal processing of iron ores. The project will investigate the contribution of iron ore to the composition, chemistry and mechanism of transformation of atmospheric volatile emissions and vapour trace elements during thermal processing with the aim to strengthen the environmental performance and efficiency of the ironmaking process.
Regrinding chemistry and particle breakage mechanisms in increased surface hydrophobicity on fine and ultra-fine particles in mineral flotation. This project will study the effect of regrinding chemistry and particle breakage mechanisms on the redistribution of flotation collectors and the evolution of the metal oxidation species on mineral surfaces. New technologies will be developed to increase mineral surface hydrophobicity and therefore increase fine and ultra-fine particle flotation.
