A Mass-Balance Tool for Monitoring Potential Dissolved Sulfur Oxidation Risks in Mining Impacted Waters

Sulfur oxidation intermediate compounds (SOIs) in mine tailings reservoir water are linked to adverse environmental impacts, such as acidity, toxicity, and oxygen consumption, and can lead to regulatory non-compliance. Their prediction and management has largely focused on a subset of SOI compounds referred to as thiosalts (SnOx2−), with thiosulfate (S2O32−) presumed to be the dominant thiosalt species, yet no published study to date has...
