High Temperature Metallurgical Processing contains the proceedings of the Second International Symposium on Thermal Processing of Minerals, Metals and Materials. This symposium explores physical and chemical transformations in materials that have been designed to facilitate the recovery of valuable metals or produce other useful materials. Representatives from both industry and academia focused on the latest innovative high temperature technologies. Because high temperature processes require high energy input, the presenters addressed the need for sustainable technologies that could provide low energy consumption and low pollution emissions. The symposium also examined the thermodynamics and kinetics of chemical reactions, phase transformations at elevated temperatures, and characterization of materials used or produced in high temperature processing.
