Electron microprobe analyses of sphalerite (ZnS) were collected on samples from current or past mining operations in the USA with a specific focus on germanium (Ge), a byproduct critical mineral recovered from sphalerite. Data and methods reported are part of a research study published here: Hayes SM, McAleer RJ, Piatak NM, White SJO, Seal RR II (2023), A novel nondestructive workflow for examining germanium and co-substituents in ZnS.
