Supernormal enrichment of cadmium in sphalerite via coupled dissolution-reprecipitation process

Communications Earth & Environment, 2023
Supernormal enrichment of cadmium in sphalerite is frequently observed in some sedimentary-hosted zinc-lead deposits, although related fluid process remains unconstrained.

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Kinetics of Sphalerite Leaching by MnO₂-KI Oxidation System in Sulfuric Acid

Metals
Efficient extraction of zinc from polymetallic concentrates is crucial for the metallurgical industry. Traditional leaching techniques often rely on strong oxidizing agents, which can be wasteful and environmentally harmful.

Tuning the Electronic Structure and Photocatalytic Properties in Polar Two‐Dimensional Gallium Oxide Through Interlayer Stacking and Sulfur Doping

Electron, EarlyView.
This work demonstrates that site‐selective sulfur doping effectively narrows the bandgap of polar 2D Ga2O3 monolayer while preserving the built‐in electric field, enabling efficient carrier separation and enhanced visible‐light absorption for photocatalytic water splitting.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Study on the Selective Inhibition of FeSO₄-NaH₂PO₄ in Sphalerite–Pyrite Flotation Separation

Molecules
Sphalerite–pyrite separation has always been one of the key issues of concern in the field of mineral flotation. To achieve selective flotation separation of sphalerite and pyrite, a novel flotation system, FeSO4+NaH2PO4-CuSO4-SIBX, was adopted.
