Objectives

The main objectives of this research led module are as follows:
- To understand the physical chemistry of metal extraction and refining processes in ferrous, nonferrous and refractory metals;
- To understand the thermodynamic properties of materials, phase rule application, partial pressure diagrams and chemical potential diagrams and their construction/importance in extractive metallurgy;
- To understand the principles of electrometallurgy, FFC process, chemical sensors and their construction and applications.

Learning outcomes
Students will gain in-depth knowledge of the fundamentals of the metal extraction processes, thermodynamics and kinetics of processes, chemical sensors and their applications in extraction and refining of ferrous and nonferrous metals and recent advances in ferrous, nonferrous and refractory metals extraction processes.
