Partnership with Rio Tinto

    Description of impact

    Macquarie University has had a long-standing partnership with Hamersley Iron Pty Ltd, a wholly owned subsidiary of Rio Tinto. This partnership, led by Prof Vladimir Strezov, has focused on understanding the various potential impacts from the iron ore processing industry. The project has investigated emissions produced from iron ore processing with the focus to understand the emissions, their composition, the mechanisms leading to emissions, and differences between different ore samples, which is a priority for the industry. In earlier stages of this program, in partnership with Hamersley Iron, Macquarie University researchers studied the emission of particles during processing and explored how particles were formed and which ores produced the most particles. A key concern was to understand the chemical composition of the particles. This work was followed by a project that looked at the volatiles released during processing and how these compounds are produced. As a direct result of the collaborative investigations, Hamersley Iron, redesigned their Loss on Ignition (LOI) reporting and assessment standards, a technique used to estimate the amount of impurities in the iron ores. The new internal standard was promoted internationally and within the international ISO committee and is now accepted as a standard testing method by other laboratories and services in Australia. This partnership has led to 5 consecutive ARC Linkage grant and programs and was published by the Australian Government as a successful example for university-business collaboration in their Review for Research Policy and Funding Arrangements.
