(PDF) Sulfur Ore Deposits

ores are known collectively as sulfur-bearing raw materials. Sulfur is extracted from sulfur ores by a mining process (10–20% of world. production) and a geotechnological process ( 90–80%). In ...

Microbially mediated sulfur oxidation coupled with arsenate …

Genome mining further expanded the list of potential SOAsRB to diverse phylogenetic lineages such as members associated with Burkholderiaceae and Rhodocyclaceae. Metagenome analysis using multiple tailing samples across southern China confirmed that the putative SOAsRB were the dominant As(V) reducers in these sites.

Multi-Stage Metallogenesis and Fluid Evolution of …

The Hongtoushan Cu-Zn volcanogenic massive sulfide (VMS) deposit, located in the Hunbei granite–greenstone terrane of the North China Craton, has undergone a complex, multi-stage metallogenic evolution. The …

High-resolution maps of critical loads for sulfur and nitrogen …

However, based on Duan et al.'s results, Zhao et al. found that the critical load exceedance of sulfur remained at 2.5 Mt in 2015, and that of nitrogen was 1.1 Mt 22. …
