Kinetics of stibnite (Sb2S3) oxidation at roasting temperatures [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2014
Experimental work on the oxidation of stibnite (Sb2S3) was carried out at temperatures between 350 and 500°C and oxygen partial pressures between 1.01 and 21.28 kPa by using a thermogravimetric analysis method. The oxidation rate of stibnite was

Stibnite froth flotation: A critical review [PDF]

Minerals Engineering, 2021
Antimony has a long and diverse history of applications, and concerns about its future supply have emerged in recent years. Stibnite-bearing ores continue to be the main source of this critical element, although its sourcing from secondary resources (e.g. mine tailings) is becoming increasingly relevant yet technically challenging. In this sense, froth

Mineralogy, Geochemistry and Fluid Inclusion Study of the Stibnite Vein-Type Mineralization at Rizana, Northern Greece

Geosciences, 2023
The stibnite mineralization at Rizana (Kilkis ore district; Serbo-Macedonian metallogenic province; northern Greece) occurs along a NE–SW-trending brittle shear-zone, which transects a two-mica and an augen-gneiss of the Vertiskos Unit. Barren Triassic A-

Potentially Toxic Elements in Terrestrial Mosses in the Vicinity of a Stibnite Mine in Pinal de Amoles, Mexico [PDF]

Plants
Mining waste often contains elevated concentrations of V, Cr, As, Sb, and Pb. Stibnite mining, during extraction and processing, generates waste that is deposited directly onto soil without vegetation cover, potentially leading to environmental pollution.

The promotion effect of FeS2 on Sb2S3 bioleaching and Sb speciation transformation [PDF]

Frontiers in Microbiology
Stibnite (Sb2S3) is an important but difficult to biologically leach mineral, so it is important to find a potential scheme for improving the bioleaching rate of Sb2S3.

On-Surface Synthesis of B₃N₃-Substituted Two-Dimensional Covalent Organic Frameworks with Distinct Pore Sizes and Kagome Band Structures. [PDF]

Small
Single‐layer, 2D BN‐substituted covalent organic frameworks (COFs) with two distinct periodicities are synthesized on noble metal supports. A multi‐method characterization reveals a non‐planar, chiral structure. Band gaps and frontier band dispersion are controlled by linker chemistry and spacer extension.

Upcycled PET-Derived Carbon Foam Functionalized with Cu₃SbS₄-Sb₂S₃ Heterostructures for Efficient Interfacial Solar Desalination. [PDF]

Small
Carbon foam is upcycled from waste PET and decorated hydrothermally with Cu3SbS4‐Sb2S3 to prepare a photothermal evaporator. The Cu3SbS4‐Sb2S3/CF reveals superior photothermal performance with excellent evaporation rate under one‐sun radiation. This renewable‐based sustainable strategy enables circular economy practices that suggest a promising ...
