Why Sulphur?

As sulphur rich ores are processed and metals are extracted, large volumes of waste rock and tailings are deposited into oxidation reservoirs/ponds. These deposits are of environmental concern as acidity and thiosalts (sulfur oxidation intermediates) can produce toxicity that may affect the ecological health of receiving environments, such as creeks, rivers and lakes.

We continue to develop monitoring and decision-making tools that support efficient mining wastewater management. Our research goals remain focused on finding ways to reduce risks of environmental impacts, and to lower costs and liabilities for the industry, while protecting Canadian freshwater resources.

The problem, the current practice and our approach to find a solution.
