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

open access: yesFrontiers in Microbiology, 2017
Sulfur compounds in intermediate valence states, for example elemental sulfur, thiosulfate, and tetrathionate, are important players in the biogeochemical sulfur cycle. However, key understanding about the pathways of oxidation involving mixed-valance state sulfur species is still missing.

Carbon footprint and atmospheric pollutant emissions accounting of an open-pit coal mine in China and its reduction pathways

open access: yesMeitan xuebao
The coal industry is a key area for pollution reduction and carbon mitigation in China. Clarifying the emission characteristics of CO2 and air pollutants during the coal mining process is crucial for achieving carbon peak and carbon neutrality. A typical

Sulfur from the Stari trg mine, Kosovo

open access: yesNatura Croatica : Periodicum Musei Historiae Naturalis Croatici, 1992
Sphalerite, pyrite, bournonite, boulangerite, anglesite and sulfur were determinated on one sample of the ore deposit of Stari Trg mine, kept in collection of Department of Mineralogy and Petrography, Croatian Natural History Museum. Relation of the deposition of found minerals was determinated. Sulfur was deposited as fine powder coatings and as small

Deciphering the prokaryotic community and metabolisms in South African deep-mine biofilms through antibody microarrays and graph theory.

open access: yesPLoS ONE, 2014
In the South African deep mines, a variety of biofilms growing in mine corridor walls as water seeps from intersections or from fractures represents excellent proxies for deep-subsurface environments.

Evaluating Coal Quality and Trace Elements of the Karagandy Coal Formation (Kazakhstan): Implications for Resource Utilization and Industry

open access: yesResources
The Carboniferous coal seams in Northeast Kazakhstan remain insufficiently investigated, with a lack of comprehensive mineralogical and geochemical assessments necessary to understand the geological processes controlling coal quality. This study examines

Mineralogical and elemental analysis of Kazakh coals from three mines: Preliminary insights from mode of occurrence to environmental impacts

open access: yesOpen Geosciences
This study aims to comprehensively characterize coal extracted from three active mines in northeastern Kazakhstan: Lenin, Saradyr, and Bogatyr. These mines exploit two Carboniferous coal-bearing formations, Dolyn and Karagandy.
