A novel non-destructive workflow for examining germanium and co-substituents in ZnS

Frontiers in Earth Science, 2023
A suite of complementary techniques was used to examine germanium (Ge), a byproduct critical element, and co-substituent trace elements in ZnS and mine wastes from four mineral districts where germanium is, or has been, produced within the United States.
