Review: Removal of Thiosalt/Sulfate from Mining Effluents …
Thiosalts have relatively low toxicity, however sulfate formed from the degradation of thiosalts, leads to pH depression in receiving water bodies creating toxic conditions for aquatic organisms. Therefore, proper management and treatment of mining effluent water containing thiosalts is critical.
