Cost-effective, sustainable and responsible extraction routes
for recovering distinct critical metals and industrial minerals
as by-products from key European hard-rock lithium projects

Quentin Dehaine is a Senior Researcher at the GTK with strong expertise on ore mineralogy, mineral processing and geometallurgy of battery metals (Cobalt, Lithium notably) and critical raw materials (CRMs) such as Rare Earths Elements (REEs). He is particularly interested in the integration of geology, mining engineering, mineral processing and metallurgy through the application of geometallurgy. More globally, the focus of his research is to develop innovative integrated approaches to support mine value chain optimisation, responsible sourcing, reduce technical risk, maximize resource efficiency and minimize environmental impacts. Quentin holds an engineering degree from the Ecole Nationale Supérieur de Géologie (ENSG) and a PhD from the Université de Lorraine. Before joining GTK, he was a postdoc at the Camborne School of Mines. His expertise also covers traceability, waste valorisation, Theory of Sampling (TOS) and process modelling.
