Hydrometallurgy and Corrosion (Hydromet)

The research group is dedicated to enabling sustainable living for future generations. As a result of the increased utilisation of electrification, automation, renewable energy solutions and the continued rise in living standards, numerous challenges related to the primary production and circular economy of metals have appeared. By the combination of the theoretical understanding of hydrometallurgy, electrochemistry, corrosion prevention, process development, process modelling, LCA analysis and state of the art analysis techniques, our researchers are at the forefront of sustainable industrial process development. Furthermore, Hydromet’s extensive collaboration with a wide variety of industrial and academic stakeholders enables the pioneering of new innovative solutions for these crucial global challenges.
