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. The project will use an integrated approach to demonstrate, experiment ....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. 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
Differential solidification of steel slag to create a fertiliser co-product. The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and product ....Differential solidification of steel slag to create a fertiliser co-product. The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and production of a phosphorus rich co-product for agriculture. Benefits are anticipated to include increased utilisation of steel slag, creation of a valuable fertiliser co-product, decreased greenhouse gas emissions, and a reduction in the penalty applied to Australian iron ores.Read moreRead less
Multiscale study of raceway operations for low-cost and stable ironmaking. This project aims to optimise blast furnace operations and to assess the performance of Australian brown coals in ironmaking. Pulverised coal injection is a cost-effective technology in blast furnace ironmaking, particularly if low-grade coal is used. This project aims to develop control strategies for stable and low-cost operation and to assess and optimise the combustion of brown coal and its blends in this process.

Pulverised coal injection is a cost-effective technology in blast furnace ironmaking, particularly if low-grade coal is used. This project aims to develop control strategies for stable and low-cost operation and to assess and optimise the combustion of brown coal and its blends in this process. The project aims will be achieved via multiscale modelling and simulation, supported by laboratory and plant experiments. The outcomes of the project are intended to open a new market for brown coal.Read moreRead less
Development and application of a virtue experimental blast furnace. This project aims to develop a virtual experimental blast furnace based on advanced discrete particle simulation technique. It is intended that the model furnace will be used to study the flow and thermochemical behaviour in iron making, quantify the effects of key variables related to raw material and operational conditions, and formulate strategies for optimum process design and control under different conditions. The findings ....Development and application of a virtue experimental blast furnace. This project aims to develop a virtual experimental blast furnace based on advanced discrete particle simulation technique. It is intended that the model furnace will be used to study the flow and thermochemical behaviour in iron making, quantify the effects of key variables related to raw material and operational conditions, and formulate strategies for optimum process design and control under different conditions. The findings aim to be very useful to comprehensively assess the performance of Australian minerals in iron making, improve the energy efficiency and reduce carbon dioxide emission in the steel industry, and enhance the competitiveness of the Australian economy.Read moreRead less
Model studies of new ironmaking processes. This project aims to study the fundamentals governing the multiphase flow and thermochemical performance in representative new ironmaking processes, and formulate some useful strategies for the design, control and optimisation of next generation of ironmaking technology which is useful to Australia's future mineral and steel industries.
