Influence of Terpenic Oil on Flotation Behavior of Sphalerite and Implication for the Selective Separation

open access: yesAdsorption Science & Technology, 2021
Terpenic oil (TO) is commonly used as a flotation frother for the selective separation of sulfide minerals. As a frother, most reports have mainly focused on its effect on froth stability and froth entrainment, whereas its influence on the floatability ...

Tuning the electronic and optical properties of the sphalerite by adsorbing halogen and alkali metals

open access: yesIET Optoelectronics, 2021
TThe electronic and optical properties of sphalerite (ZnS) are modulated by adsorbing alkali metals (Li, Na, K, Rb, Cs) and halogen (F, Cl, Br, I, At). Simulations based on density‐functional theory are used to study the electronic and optical properties

Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]

open access: yes, 2019
The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...

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.
