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

This project involves a fundamental study of the kinetics of reactions that occur in solvent extraction processes used for separation of many of Australia's metals from minerals. The understanding gained from this will enable a greater efficiency to be obtained from Australia's minerals industry. In particular, it is intended to investigate the role of additives on the kinetics of metal extraction; these additives either enter the solution from the ore or are added as flocculants during the process, and have a significant effect on the performance. With the move to smaller, shorter residence time contactors, this has become increasingly important if these new contactors are to be used efficiently.Read moreRead less

Improving iron ore agglomeration by studying underlying mechanisms using experimental studies and dimensional analysis. The revenue from Australia's iron ore exports is currently worth over $15 billion. Over 80% of the shipped ores are fines (ie material smaller than 9mm), which have to be sintered to produce a lumpy product prior to reduction and smelting in iron making blast furnaces. An understanding of this process at the fundamental level is essential for enhancement of the nation's technol ....Improving iron ore agglomeration by studying underlying mechanisms using experimental studies and dimensional analysis. The revenue from Australia's iron ore exports is currently worth over $15 billion. Over 80% of the shipped ores are fines (ie material smaller than 9mm), which have to be sintered to produce a lumpy product prior to reduction and smelting in iron making blast furnaces. An understanding of this process at the fundamental level is essential for enhancement of the nation's technological standing with our key trading partners - that is, to enable Australian iron-ore exporters to become 'knowledgable' suppliers. In addition, local iron-making industries will gain direct economic benefit from the improved sintering processes developed. Read moreRead less

Influence of adsorbed surfactants on three phase contact line motion at high capillary number. The interaction between thin films and solid surfaces underpins the performance of a number of value-adding industrial processes, most notably metallurgical coating operations. Typically, these operations are performed at speeds well beyond the range of existing models, thereby limiting their value when changes in operation occur or when there are problems with product quality. Existing models are also ....Influence of adsorbed surfactants on three phase contact line motion at high capillary number. The interaction between thin films and solid surfaces underpins the performance of a number of value-adding industrial processes, most notably metallurgical coating operations. Typically, these operations are performed at speeds well beyond the range of existing models, thereby limiting their value when changes in operation occur or when there are problems with product quality. Existing models are also limited by their inability to account for the presence of surfactants commonly used throughout industry. This study will produce a capability for predicting how velocity and local changes in molecular composition affect the wetting/dewetting of coated surfaces.Read moreRead less
