Abstract:

Nature-based solutions: Addressing thiosalts management and treatment inefficiencies

Sulfur compounds capable of oxidation, e.g., thiosalts (SnOx2-), are common by-product of operations processing sulfide minerals. They remain a global mining environmental challenge linked to impacts such as ARD and toxicity failures; indicating biological knowledge gaps contribute to on-going sulfur risks. Case study results of a 5-year sulfur biogeochemical investigation of four Canadian base metal mine tailings impoundment (TI) and receiving environment (RE) waters, reveal extensive microbial sulfur cycling directly linked to acidity and reactive sulfur outcomes. Identified conditions and controls on these microbial sulfur oxidation reactions are not captured in current model and management strategies, underscoring the need for biogeochemical investigation to improve sulfur related RE outcomes. Attendees will gain a biologically informed perspective in this lecture that will demonstrate how such microbially integrated investigation addresses long-standing critical sulfur knowledge gaps, and paves the way for development of smart, nature-based sulfur solutions.
