Model studies of Australian lump ore applied to blast furnace ironmaking. Ore lump use in ironmaking blast furnaces (BFs) requires no preprocessing and has a lower carbon footprint. However, it suffers various technical problems. This project aims to understand and optimize the conditions for such operations. This will be achieved by means of a combined theoretical and experimental program, involving the use of state-of-the-art multiscale computer modelling and simulation techniques.

However, it suffers various technical problems. This project aims to understand and optimize the conditions for such operations. This will be achieved by means of a combined theoretical and experimental program, involving the use of state-of-the-art multiscale computer modelling and simulation techniques. The research outcomes will be tested in the design and control of lump charging operations in practice through collaboration with the industrial partner. This will ultimately increase Australian ore lump usage in BFs, leading to significant financial and environmental benefits to Australia and the entire steel industry worldwide.Read moreRead less
Coke integrity in blast furnace ironmaking: understanding and technology development. This project's expected outcomes will lead to optimised coke consumption for the blast furnace and to a more competitive steel manufacturing sector, through improved and rational criteria for selection of carbonaceous materials. This will result in more efficient ironmaking with significant operational, economical and environmental benefits.
Thermodynamic basis for ironmaking and slag recycling in circular economy. This project aims to develop new, powerful state-of-the-art computer-based tools to predict the outcomes of complex chemical reactions, high-temperature ironmaking and slag recycling processes. Globally, over 1 billion tonnes of iron are produced each year consuming 30 billion billion (Quintillion) Joules energy! and creating over 300 million tonnes of molten oxides (slags). Our industry partners need new advanced thermod ....Thermodynamic basis for ironmaking and slag recycling in circular economy. This project aims to develop new, powerful state-of-the-art computer-based tools to predict the outcomes of complex chemical reactions, high-temperature ironmaking and slag recycling processes. Globally, over 1 billion tonnes of iron are produced each year consuming 30 billion billion (Quintillion) Joules energy! and creating over 300 million tonnes of molten oxides (slags). Our industry partners need new advanced thermodynamic databases and computer models with which to optimise their major industrial processes and develop new technologies. By delivering these tools, this project expects to benefit both industry and the community through improved process efficiencies, and reductions in energy usage, pollutants, and environmental impacts.

The use of Australian magnetite ore in advanced ironmaking. The project will study reduction behaviour of Australian magnetite ore in advanced ironmaking with low emission of greenhouse and hazardous substances. Efficient utilisation of magnetite ore which economic demonstrated resources constitute 9.5 gigatonnes will be of high importance to Australian industry and prosperity.
Tectonothermal and mineralization history of banded iron formations of the north Pilbara Craton. Iron ore is Australia's largest single export commodity, accounting for 8% ($12.8 billion) of total merchandise exports in 2006. Most of that value comes from the Pilbara region of Australia. Discovery rates of new deposits have declined over the past two decades, while many mines are nearing the end of production. Exploration expenditure has also declined. There is therefore an urgent need to reinvi ....Tectonothermal and mineralization history of banded iron formations of the north Pilbara Craton. Iron ore is Australia's largest single export commodity, accounting for 8% ($12.8 billion) of total merchandise exports in 2006. Most of that value comes from the Pilbara region of Australia. Discovery rates of new deposits have declined over the past two decades, while many mines are nearing the end of production. Exploration expenditure has also declined. There is therefore an urgent need to reinvigorate exploration to maintain an industry that underpins much of Australia's regional wealth. Outcomes of the project will provide exploration with improved geological tools with which to develop superior exploration models and thereby better direct exploration strategies.Read moreRead less
Thermal characterisation of iron ores and coals for HIsmelt operation. Substantial developments in direct reduction ironmaking (DRI) have been recently conducted providing sustainable way for metallurgical operations. The largest advantage of DRI is that it does not require cokemaking and sintering, two processes which are consistently causing environmental concerns. This project aims to thermally investigate coals and iron ores for optimising direct smelting, and to provide insight into effect ....Thermal characterisation of iron ores and coals for HIsmelt operation. Substantial developments in direct reduction ironmaking (DRI) have been recently conducted providing sustainable way for metallurgical operations. The largest advantage of DRI is that it does not require cokemaking and sintering, two processes which are consistently causing environmental concerns. This project aims to thermally investigate coals and iron ores for optimising direct smelting, and to provide insight into effect of the properties of ores and coals on the process. Structural changes using hot stage optical microscopy will be carefully clarified. Finally, a predictive model for DRI and energy requirements for direct smelting based on the experimental outcomes will be developed.Read moreRead less
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.

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

Open pit mine design and production scheduling (OPDPS) deals with the management of cash flows in the order of hundreds of millions of dollars, and is a critical aspect of mining ventures. To enhance decision-making under conditions of uncertainty, this proposal aims to develop a new methodology for OPDPS based on mathematical and statistical techniques which model uncertainty in key parameters, geological, mining and market/cost and their effects on economic forecasts. The new formulation is founded on stochastic integer programming, and its integration with spatial stochastic simulations of geological attributes. Methods developed are computerised and tested in field studies.Read moreRead less
