Dr Alexander Kiy
Postdoctoral Fellow
The Australian National University

Hydrogen reduction of iron ore: Insights from 3D analysis

11:15 AM - 11:30 AM

Biography

Dr. Alexander Kiy completed his PhD at the Australian National University in 2023, where he developed conical nanopores in silicon dioxide membranes and studied how their shape and surface charge affect ion transport. His work combined experiments and modelling to explore applications in sensing, filtration, and energy systems. As a materials scientist, he is now specialising in sustainable metallurgy with expertise in developing low-carbon ironmaking technologies through hydrogen-based reduction to produce direct reduced iron (DRI). His current research involves employing advanced analytical tools like micro-computed tomography (µCT), SEM, XRD, and XRF to investigate structural changes and degradation behaviours in iron ores, aiming to optimise process conditions for efficient, low-emission iron production and support global decarbonisation goals in the steel industry.

Dr Banty Kumar
Post Doctoral Fellow
CSIRO

Experimental study on the melting behaviour of different forms of H2 DRI in electric smelting furnace-type slags

11:45 AM - 12:00 PM

Biography

Dr. Banty Kumar is a Postdoctoral Researcher at CSIRO, Melbourne, specializing in sustainable ironmaking, waste recycling, and process metallurgy. He earned his Ph.D. in Metallurgical and Materials Engineering from the Indian Institute of Technology Kharagpur, where he also completed his M.Tech. degree, after obtaining his B.Tech. from the National Institute of Technology Jamshedpur. His doctoral research focused on the reduction behavior of off-grade iron ore fines and electric arc furnace dust (EAFD)–carbon composite pellets. Dr. Kumar integrates experimental investigation with thermodynamic modeling using FactSage to develop low-carbon and resource-efficient metallurgical processes. He has authored several peer-reviewed publications, holds a patent, and has presented his work at national and international conferences. Experienced in advanced characterization techniques such as XRD, SEM, XRF, and XCT, he continues to contribute to cleaner and more sustainable technologies for the iron and steel industry.

Mr Abrar Taimullah
Phd Scholar
University of Newcastle

Thermodynamic assessments of Australian iron ore DRI smelting in a laboratory-scale electric smelting furnace

12:07 PM - 12:14 PM

Biography

Abrar Taimullah is a PhD student with a strong passion for developing low-carbon and green metallurgical technologies through a combination of experimental research and thermodynamic modelling. His previous work focused on hydrogen plasma smelting reduction as a sustainable and rapid technology for producing ferronickel, ferrochrome, and stainless steel. Currently, he is investigating DRI-ESF technology for low-carbon ironmaking, focusing on laboratory-scale smelting experiments to optimise hot metal production from medium-grade iron ore DRI, while examining the mechanisms of carburisation and silicon transfer in ESF. He is also developing FactSage thermodynamic modelling to understand metallurgical processes occuring in DRI smelting in ESF.
