 | Biography |  |
Professor Peter Hayes's research focuses on the high temperature processing of minerals and materials, with particular application to the pyrometallurgical production and refining of metals. His interests include chemical equilibria, reaction kinetics and mechanisms. He received his PhD from the University of Strathclyde in Glasgow, Scotland, in 1974. He is currently Metallurgy program leader and Senior researcher in the Pyrometallurgy Research Centre (PYROSEARCH) in UQ's School of Chemical Engineering.
His current research projects encompass:
• Phase equilibrium measurements and determination of liquidus isotherms in complex industrial slag systems relevant to the smelting of copper, ferro-chromium, ferro-manganese, iron, ferro-nickel, lead, zinc and to coal ash slags.
• The development of thermodynamic models, and their use in conjunction with Fact Sage, to predict phase equilibria and thermodynamic properties in oxide systems.
• Reaction kinetics and mechanisms in metal smelting and refining. In particular, reactions between carbon and metallurgical slags during lead, ferro-chromium, ferromanganese and zinc smelting.
• Slag viscosity measurement and prediction in fully and partially molten slag systems.
• Examination of lead and zinc sinter microstructures, and the associated sintering processes to determine key process variables and their effect on sinter properties.
