The Structures of Elemental Sulfur [PDF]

, 1976
Publisher Summary Elemental sulphur is commonly known and widely used. Its properties are already described in the Old Testament and in Homer's Odyssey. It exists in several different forms. Thermodynamically stable sulphur forms deep yellow, nonodorous orthorhombic crystals with a space group Fddd-Dh224, containing 16 molecules— that is, 128 atoms ...

Direct reduction of SO2 to elemental sulfur by the coupling of cold plasma and catalyst (I) [PDF]

, 2004
The direct reduction of SO2 to elemental sulfur in flue gas by the coupling of cold plasma and catalyst, being a new approach for SO2 reduction, was studied.

Kinetics of the reaction between elemental sulfur and silver in synthetic esters and comparison with mineral oils [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla"
For decades, the problem of corrosive sulfur was considered to be exclusively associated with mineral oils. However, recent cases from industry have disproved this assumption.

Tetrathionate and Elemental Sulfur Shape the Isotope Composition of Sulfate in Acid Mine Drainage

Frontiers in Microbiology, 2017
Sulfur compounds in intermediate valence states, for example elemental sulfur, thiosulfate, and tetrathionate, are important players in the biogeochemical sulfur cycle.

Paleoarchean sulfur cycling: Multiple sulfur isotope constraints from the Barberton Greenstone Belt, South Africa [PDF]

, 2015
Mass-dependent and mass-independent sulfur isotope fractionation archived in volcanic and sedimentary rocks from the Barberton Greenstone Belt (3550-3215. Ma), South Africa, provide constraints for sulfur cycling on the early Earth. Four different sample

Adsorption of sulfur on Lanxess Lewatit® AF 5 resin during the acidic albion leaching process for chalcopyrite

Heliyon, 2023
Elemental sulfur is one of the major byproducts of the acidic Albion leaching process for chalcopyrite. It is a challenging component in the leach solution as it impedes gold recovery from the residue. Lanxess Lewatit® AF 5 (AF 5) is a microporous carbon-

Acidithiobacillus caldus sulfur oxidation model based on transcriptome analysis between the wild type and sulfur oxygenase reductase defective mutant.

PLoS ONE, 2012
BackgroundAcidithiobacillus caldus (A. caldus) is widely used in bio-leaching. It gains energy and electrons from oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs) for carbon dioxide fixation and growth.

The producing of lead and elemental sulfur by new technologies from galenite ores [PDF]

, 2011
These investigations have developed an effective hydrometallurgical method to recover high-purity lead metal and elemental sulfur from simulated galena synthetic mixures eliminating sulfur gases and lead emissions, in contrast to the current high ...

Modeling the signature of sulfur mass-independent fractionation produced in the Archean atmosphere [PDF]

, 2014
Minor sulfur isotope anomalies indicate the absence of O2 from the Archean atmosphere. A rich dataset showing large variations in magnitude and sign of Δ33S and Δ36S, preserved in both sulfates and sulfides, suggests that further constraints on Archean ...
