Microbial Sulfur Pathways and Outcomes in Tailings Impoundments: A Mesocosm Study

In mine wastewaters, three microbial sulfur oxidation pathways have the potential to cause different water quality outcomes that can differ from abiotic model sulfate and acidity predictions, currently used to monitor potential sulfur risks. However, studies integrating microbiology and geochemistry in active mine tailings impoundments, are very limited. Here, we developed a novel diagnostic approach to detect microbially driven sulfur …
