Thermodynamics and Metallurgy: Control of Sulfur Dioxide Pressure

This lecture discusses the theoretical control of sulfur dioxide pressure in metallurgical processes, particularly at 1000°C. The instructor explains the significance of the Ellingham diagram and its application to the sulfidation reaction involving iron and copper sulfides. The lecture emphasizes the simplifications made in the initial operations of pyrometallurgical extraction of copper from sulfide-rich ores. The instructor challenges students to identify the real-life complexities that arise when considering chemical reactions, equilibria, and operational conditions. Additionally, the lecture covers the importance of understanding the relationship between thermodynamics and extractive metallurgy, highlighting the need for accurate modeling of reactions to reflect practical scenarios. The discussion includes exercises that encourage students to apply theoretical concepts to practical situations, enhancing their comprehension of the material behavior during processing. The lecture concludes with a review of the exercises assigned for the week, reinforcing the connection between theory and practice in metallurgy.
