Iron Ore Beneficiation: Technology to Upgrade Ores for Green Iron and Steel Production
We invite you to our upcoming public webinar, presented by Dr Lina Hockaday from Curtin University and Dr Alfonso Chinnici from The University of Adelaide.
Technology and processes to beneficiate iron ores is important to overcome challenges in using low-grade Pilbara iron ores in low emissions direct reduced ironmaking (DRI) and avoiding more carbon intensive blast furnaces in steel production.
Our current project RP1.011 The upgrading of iron ore for DRI production using products from seawater RO brines, led by Dr Lina Hockaday and Professor Jacques Eksteen from Curtin University, aims to improve the commercial viability of using low-grade iron ores in low emissions DRI production. The project also aims to support the circular economy by not only using waste brines to upgrade the ores, but also by generating valuable by-products. This project recently secured an additional $2.4M funding from ARENA, MRIWA and Curtin University in ARENA’s recent Iron and Steel R&D Round, to enable the technology to be taken to pre-commercial readiness.
One of our Quickstart projects led by Dr Alfonso Chinnici, RP1.006: The viability of high flux thermal pre-treatment of low-grade iron ores, showed that heating of crushed iron ore prior to grinding can yield significant net benefits in beneficiation. Building on these encouraging results, Alfonso now leads the current 1-year project RP1.008 Green pyromet/hydromet beneficiation pathways which aims to establish combined pyromet-hydromet and pyromet-magnetic separation flowsheet options with the potential to upgrade Pilbara and Whyalla fine iron ores (e.g., goethite/hematite) to lower carbon intensity while achieving higher grade ores.
This webinar presents a unique opportunity to hear from Lina and Alfonso about these groundbreaking projects, aiming to de-risk the production of green steel at scale by addressing key challenges in the iron ore beneficiation process.
SPEAKERS
Dr Lina Hockaday, Curtin University
Dr Lina Hockaday has 18 years of pyrometallurgical research experience in the non-ferrous industry. She joined Mintek in 2002 after obtaining her B. Chem.Eng. (Minerals Processing) and M.Sc. in Extractive Metallurgy at the University of Stellenbosch in South Africa.
During 2002 to 2010 Lina worked in the commercial projects group on various projects including the recovery of precious metals in liquid iron and the smelting of ores to produce design specifications of an industrial ferrochrome DC arc furnace. From 2011 to late 2015 she took a break from work and had two delightful children, now aged 13 and 10. From 2015-2021, she was involved in research of new technologies for titanium metal production, chlorination of titanium dioxides in a fluidised bed, and the applications of concentrating solar energy in mineral processing.
In 2023 Lina obtained her PhD in Mech Eng with the thesis entitled “Solar Thermal Treatment of Manganese Ores”. In June 2021, she moved to Perth, Australia with her family, and since October 2022, she has been employed at Curtin University as a senior engineer and postdoctoral research fellow executing two HILT CRC projects involving the low-carbon upgrading of iron ores.
