10:30 AM - 12:30 PM |
Speaker
Dr Mark Pownceby
Geometallurgy Team Leader
CSIRO Mineral Resources
Examining the relationship (if any) between elevated phosphorus and ore textural type in Pilbara iron ores
10:30 AM - 10:45 AMBiography
Mark joined CSIRO in 1992 as a Research Scientist. Mark’s research expertise is in the field of solid-state chemistry and mineralogy. He applies this expertise in research projects related to the characterisation of bulk iron ores and their sintered products; heavy mineral sands characterisation and processing; the mineralogy of uranium ores; recycling and sustainability; and experimental phase equilibria.
Mark has >25years experience in iron ore and in his present role his major activities involve understanding the complex mineral assemblages formed during the sintering of iron ores and in overseeing the ore characterization activities in CSIRO’s Iron Ore Geometallurgy research area. He has made significant contributions to fundamental studies of iron ore. In particular, Mark and his colleagues have brought a strong scientific understanding to the sintering behaviour of iron ores through high temperature x-ray diffraction and determination of important chemical equilibrium data for these systems. His recent research has focused on understanding the relationships between impurities and iron ore textural types.
Dr Sarath Hapugoda
Senior Experimental Scientist
CSIRO Mineral Resources
Effect of calcium oxalate CaC2O4.H2O on the Reduction and Phosphorus partition of a High-P Brockman ore
10:45 AM - 11:00 AMBiography
Sarath Hapugoda is an Experimental scientist at CSIRO Mineral Resources Flagship with educational qualifications PhD (Geology), University of Queensland, 2002, MSC (Mineralogy), Shimane University, Japan, 1995, and BSC Hons (Geology), University of Peradeniya, Sri Lanka, 1986. He works in the Carbon Steel Futures Program at Queensland Centre for Advanced Technologies (QCAT) in Brisbane, providing critical mineralogical support to a host of external and appropriation research projects in Iron and Manganese ore characterization, beneficiation, and sintering. Have expertise in a wide range of characterization techniques including SEM, EPMA, optical mineralogy and image analysis and XRD.
Dr Oluwatosin Aladejebi
Research Associate
University of Newcastle Australia
The Behaviour of Iron Ore Granules: Laboratory and Commercial Sinter Plant Granulation
11:00 AM - 11:15 AMBiography
Dr Aladejebi is a Research Associate at the Centre for Ironmaking Materials Research, the University of Newcastle. His current task in the Australian Research Council (ARC) Hub for Australian Steel Research Innovation (Steel Research Hub) is a collaborative project between BlueScope Steel and the University of Newcastle (UON). This project work will extend the current understanding of the iron ore granulation process and propose a predictive framework capable of assessing ore blends, including the addition of ultrafine concentrates. He earned his Doctor of Philosophy at the University of Wollongong where he studied the Effect of Minerals on Coke Analogue Carbon Bonding and Reactivity. He also worked as an Associate Research Fellow in the Faculty of Engineering and Information Sciences, the University of Wollongong between 2020 and 2021 where he studied Phosphorus and Iron Recovery from Steelmaking Slag for Effective Recycling.
