For example, Sb concentrations of 239, 6384, and 157 µg/L have been found in Stampede and Slate Creek watersheds (Alaska, USA), rivers around antimony mines in the Xikuangshan area (Hunan Province, China), and lakes in the South East region (Sindh, Pakistan), respectively [3,4,5]...
During the 20th century, it occurred in sporadic exploitations of minor amplitude, ceasing completely in 1971 [6]. The importance of the mineral belt of Valongo is well evidenced by the fact that the Map of Douro Mining Region (1884–1891) indicates the existence of 61 Sb Mines in the ...
In the deep source area of antimony-gold mines in southern Tibet, hydrocarbons and sulfates undergo thermochemical reduction reactions, resulting in the generation of substantial amounts of hydrogen sulfide. This hydrogen sulfide can react with organic compounds present in crude oil and natural gas, ...
