Introduction to Iron Metallurgy and the Ellingham Diagram

Understanding how metals are extracted from their ores is fundamental to chemistry and materials science. This course demystifies the thermodynamic principles behind metallurgy, making complex concepts easy to grasp. Through clear written explanations, you will transition from memorizing chemical equations to understanding the thermodynamic 'why' behind metal reduction, enabling you to predict reactions and analyze extraction processes. What you'll learn: Learn the core thermodynamic principles of metallurgy, including Gibbs free energy and entropy. Interpret Ellingham diagrams to predict the feasibility of reducing metal oxides under different temperatures. Master the step-by-step chemical reactions involved in the extraction of iron. Analyze the role of temperature, reducing agents, and slag formation. Understand modern green steel innovations, such as hydrogen-based reduction methods. The course begins with key terminology, basic concepts, and foundational definitions of ores and minerals, before guiding you through thermodynamic plots and the practical steps of iron extraction. This course is designed for beginners starting their journey in chemistry or materials science, with no prior advanced prerequisites.
