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

Литосфера, 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.

Enhanced photocatalytic activity of calcined natural sphalerite under visible light irradiation

Journal 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 ...

Ab initio energies of nonconducting crystals by systematic fragmentation [PDF]

, 2015
A systematic method for approximating the ab initio electronic energy of molecules from the energies of molecular fragments has been adapted to estimate the total electronic energy of crystal lattices. The fragmentation method can be employed with any ab

Geophysical investigation of the Pb-Zn deposit of Lontzen-Poppelsberg, Belgium [PDF]

, 2018
The drillhole information from the Lontzen-Poppelsberg site has demonstrated three orebodies and has allowed the estimation of the extension of the lodes, their dip, and the location at the ground surface.
