Objectives

This course aims to teach the following topics with in-depth analysis of the chemical principles beneath the related subjects and with numerous example problems covering the subject materials in the field of electrometallurgy. To describe the principles and practice of electrometallurgical and other electrochemical processes that are, or could be, used in the production of metals.

This course aims to give students an in-depth understanding of the fundamental electrochemical principles and to show the applications of these principles in electrometallurgy through numerous example problems. The course content may be roughly equivalent to the scope of the electrometallurgy chapter of a textbook in the field of extractive metallurgy; however, the approach will be more comprehensive and in-depth, and will involve less mathematics.
