WG2 : Physicochemistry of leaching and purification processes (Leaders : D. Bourgeois, ICSM and L. Filippov, Georessources).

Hydrometallurgy is currently facing many challenges related to metals supply, the need to exploit new deposits (low-grade ores, secondary streams, urban waste...), the needs of more efficient and more environmentally friendly processes. There are many technological challenges and barriers in chemistry and physicochemistry associated with these processes and especially in leaching processes after ore processing, liquid-liquid and liquid/solid extraction and precipitation.

The fields of research of this WG are divided into several themes:
