Our industrialised society is currently facing significant challenges including resource scarcity, mobility issues, climate change. For pyrometallurgical processes these issues can be directly translated into increasingly complex concentrates and recycling feed streams with increasing levels of impurities that require complex metallurgical solutions; pressures to save energy, to increase productivity, to improve environmental outcomes and to establish resource resilience in a clean world with the optimised asset base. Improvements in the metal production and recycling can be made through more energy efficient metal smelting technologies, progressive integration of primary metal production and recycling, development and implementation of feed forward control and optimisation of pyrometallurgical processes based on fundamental thermodynamic and phase equilibria principles. Key to the development of the feed forward approach and process optimisation is access to accurate and robust thermodynamic models of complex multi-component, multi-phase systems that are developed through an integrated, experimental phase equilibria and thermodynamic modelling approach. New strategic opportunities for industry are now available through the recent significant progress in computer power and analytical tools as well as advances in thermodynamic and kinetics theory, and experimental methodology. Using new experimental methods key data are being obtained and advanced thermodynamic computer-based models are being developed for both copper and lead smelting systems having major elements Cu-Pb-Fe-S-O-Si with the addition of slagging elements Al, Ca, Mg and selected minor elements, including, Zn, As, Sn, Sb, Bi, Ag, Au. The copper research program is supported by a consortium of industry sponsors. Examples of the new experimental and modelling results as well as application of these advanced tools to achieving productivity improvements and energy savings are given in the paper.
