Data-driven monitoring of raceway dynamics in ironmaking blast furnaces. Raceway dynamics in ironmaking blast furnaces affect operational stability and cost considerably, yet their dynamic behaviour has not been well monitored online. The project aims to develop a data-driven model for monitoring the internal state of gas-solid-powder reacting flow in the raceway and predicting raceway anomalies online. It will be achieved by combining particle-fluid numerical simulations with data processing an ....Data-driven monitoring of raceway dynamics in ironmaking blast furnaces. Raceway dynamics in ironmaking blast furnaces affect operational stability and cost considerably, yet their dynamic behaviour has not been well monitored online. The project aims to develop a data-driven model for monitoring the internal state of gas-solid-powder reacting flow in the raceway and predicting raceway anomalies online. It will be achieved by combining particle-fluid numerical simulations with data processing and reduced-order state observer, supported by lab/plant experiments, and collaborating with two industry partners from coal and steel industries. The project outcomes including codes, models and raceway control strategies can help promote Australian metallurgical coal's global markets and ultimately the Australian economy.Read moreRead less
Preparation and use of lignite-iron ore composite briquettes for ironmaking. Preparation and use of lignite-iron ore composite briquettes for ironmaking. This project aims to study the briquetting processes of fine powders, and the preparation and utilization of new brown coal (lignite)–iron ore composite briquettes in a blast furnace. Lignite is a low-cost and abundant resource, and could be used in an emerging carbon-iron ore composite briquette for low-cost ironmaking.

This project aims to study the briquetting processes of fine powders, and the preparation and utilization of new brown coal (lignite)–iron ore composite briquettes in a blast furnace. Lignite is a low-cost and abundant resource, and could be used in an emerging carbon-iron ore composite briquette for low-cost ironmaking. This project will perform multi-scale numerical studies, supported by lab/industry-scale experiments, to produce models and control strategies. Anticipated outcomes include better design and control of briquette's preparation and utilization in ironmaking for further cost-cutting; a new market for brown coal; and a more competitive Australian economy.Read moreRead less

The process of hot-dip metal coating of steel has evolved to provide reliable products that find widespread application in many industries, including building and construction. This project aims to address and understand an intermittent processing problem using innovative approaches involving characterisation by synchrotron techniques and state-of-the art microscopy. Expected outcomes include increased manufacturing efficiencies by identifying the cause of an intermittent processing defect and implementing methods of controlling this defect. This will help BlueScope and Australia maintain a world-leading reputation for high-quality coating products for domestic and export markets.Read moreRead less
Safe Emulsion Explosives for High Temperature Deep Level Mining. This project aims to develop a new class of emulsion explosives, which are not susceptible to hot and reactive rock conditions in very deep-level ore mines. These emulsions will contain a tuneable polymer network to prevent collapsing of the emulsion columns in hot upholes in high temperature mines, along with additives to eliminate the exothermic reaction with the rocks. If not prevented the reaction can cause premature detonation ....Safe Emulsion Explosives for High Temperature Deep Level Mining. This project aims to develop a new class of emulsion explosives, which are not susceptible to hot and reactive rock conditions in very deep-level ore mines. These emulsions will contain a tuneable polymer network to prevent collapsing of the emulsion columns in hot upholes in high temperature mines, along with additives to eliminate the exothermic reaction with the rocks. If not prevented the reaction can cause premature detonation or deflagration of the emulsion causing fatal injuries and generation of toxic NOx gases. Increase in economically and safely extractable deep-level ore volume that generates greater export earnings and more jobs are expected project outcomes, as is reduced atmospheric pollution.Read moreRead less
Improving the processing of low-grade copper ores . The project aims to investigate the electrochemical interaction occurring during the grinding of low-grade copper ores and understand how the interaction affects the recovery of copper minerals and rejection of waste minerals in the subsequent separation process.

The project aims to investigate the electrochemical interaction occurring during the grinding of low-grade copper ores and understand how the interaction affects the recovery of copper minerals and rejection of waste minerals in the subsequent separation process. This project expects to generate new knowledge in the area of minerals processing and materials engineering using interdisciplinary approaches. Expected outcomes of this project include cost-effective new steel products used for grinding copper ores and new chemical solutions to selectively reject waste minerals during mineral separation. This should significantly reduce the operating costs in copper processing plants and increase the copper production from low-grade copper ores.Read moreRead less

The mining industry is processing low-grade ores associated with high amounts of waste minerals. Extracting metals from low-grade ores is very difficult with technical challenges in rejecting waste minerals. This project aims to understand the surface properties and the behaviour of a major waste mineral which is becoming increasingly problematic during the processing of copper and gold ores. New chemistry and chemical reagents will be developed to efficiently and economically reject the waste mineral by manipulating the reactions that take place on its surface. This project expects to have immediate economic and environmental impacts through increasing metal production, cutting greenhouse gas emissions and applying new green reagents.Read moreRead less
