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

open access: yesFrontiers 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.

The substitution mechanism of Au in In-, Fe- and In-Fe-bearing synthetic crystals of sphalerite, based on the data from EPMA and LA-ICP-MS study

open access: yesЛитосфера, 2019
Research subject. Sphalerite (ZnS) is a widespread mineral that can be found in various depositional environments. During formation, this mineral can accumulate minor and trace impurities, with gold being one of the most valuable component.

Nanoscale distribution of Ge in Cu-rich sphalerite [PDF]

open access: yes, 2023
A large proportion of the critical elements resources Ge, Ga, and In are associated with sphalerite in Pb-Zn ore deposits. Germanium in sphalerite has been proposed to be structurally bound in the crystal lattice.

Enhanced photocatalytic activity of calcined natural sphalerite under visible light irradiation

open access: yesJournal of Materials Research and Technology, 2017
The photocatalytic activity of natural sphalerite (the main mineral ore of ZnS) is relatively low in the absence of sacrificial donors. Present work focuses on the improvement of the photocatalytic activity of a natural sphalerite obtained from Abuni ...
