24/10/2024: Introduction to hydrometallurgy

This session has its focus on an introduction and overview of hydrometallurgical processes used in metallurgical industry. Starting from the thermodynamic principles in hydrometallurgy, an insight in the mechanisms of different hydro processes is given. The relevant diagrams are discussed, and the links between the principles, the chemical reactions, and the application in flowsheets for production of different metals is made.


  • 09.00: Registration
  • 09.30: Introduction in hydrometallurgy
  • 10.00: Leaching
    • Leaching reactions
    • Pourbaix diagram (E-pH diagram)
    • Reaction kinetics
  • 12.00: Sandwich lunch
  • 13.00: Purification
    • Precipitation and hydrolysis
    • Reduction potential
    • Solvent extraction
    • Ion exchange
  • 14.00: Metal recovery
    • Cementation
    • Electrowinning
    • Electrorefining
  • 15.00: Flowsheets
  • 15.30: Opportunity for discussion


After the course all participants have an overview of different processes in hydrometallurgy and understand the chemical principles behind these processes. They can make the link between the most relevant diagram and the reactions in some main industrial processes.


The course will tackle the theory of the topics listed above and an interactive approach including questions is applied to ensure that everything was understood. Due to the multitude of metals and flowsheets, a number of examples may be selected for the course, with other course material to be studied at home. An emphasis will be put on the sectors of course participants.

Who should attend

The course will be given in English and aims at people active in the metal processing industry. The course can be a refreshment of the metallurgical principles for engineers, or give hands-on metallurgists a solid theoretical background.


600 € per person per day (excl. VAT)
2000 € per person for the full course program (4 days) (excl. VAT)
