Thermodynamic and kinetic considerations of the carbothermic reduction of ores based on iron and copper oxides
Year: 2024
Type: conference-paper
Abstract: The chemical reduction of iron ores has played a significant role in human history for thousands of years, dating back to the Iron Age. This presentation focuses on carbothermic reduction in the solid state and explores the potential to use iron oxides as a secondary source of iron and energy. Various mechanisms for the interaction of solid reactants at temperatures below 1000°C are discussed. An emphasis is given to the potential of carbothermal dissociation of iron and copper oxides based on a process mechanism involving dissociative evaporation and simultaneous condensation of the product. The presentation also includes kinetics modeling, calculations of main kinetic parameters, and theoretical thermodynamic calculations. It concludes with a discussion on the potential of extracting other valuable metals from oxides by using the carbothermic reaction in the solid state.
