Overview

Biography:

Prof Hayes is Professor of Metallurgical Engineering within the School of Chemical Engineering. He is currently the Metallurgical Engineering Program leader and is senior researcher in the Pyrometallurgy Research Group (PYROSEARCH). He received his PhD from the University of Strathclyde in Glasgow, Scotland, in 1974.

Research:

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.

His current research projects encompass:

  • High temperature 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 FactSage, to predict phase equilibria and thermodynamic properties in oxide systems.
  • Reaction kinetics and mechanisms in metal and materials processing, smelting and refining; in particular, gas/solid reactions.

Teaching and Learning:

Prof Hayes’ teaching interests include pyrometallurgy, chemical thermodynamics, and physical and chemical processing of minerals.

He is author of the textbook “Process Selection in Minerals and Materials Production” by P.C. Hayes, Hayes Publishing Co, Sherwood, Brisbane, 3rd ed. 2004, and has been activity involved in program and curriculum development in the field of metallurgical engineering over a several decades.

Projects:

  1. A novel low-energy process route for primary copper production utilising synergistic hydro- and pyrometallurgical processes.
  2. The significant impacts of morphological and interface stability on gas/solid reaction kinetics and for metals production.
  3. Phase equilibria studies and the formation of iron ore sinters for the iron blast furnace.
  4. Fundamental experimental and modelling studies of slag/metal/gas systems in support of sustainable copper smelting and converting technologies.
