Supergene ore deposits: mineralogy, geochemistry and critical elements deportment 

Supergene ore deposits, like bauxites, Ni-laterites and Zn-Pb-V, Cu nonsulfides, are commonly exploited for Al, Ni, Zn, V and Cu. However, they also contain several “critical” elements (REE, Sc, Co, Ge, Ga, In), which are not recovered from these ores because their amounts and deportment are not completely known, or economically viable extraction flowsheets are not available. This session is open to contributions on mineralogy and geochemistry of supergene ores, with particular attention to studies on critical elements distribution in these deposits.
