Grant: Applied Research and Development Grants - Level 1

Mining activities are one significant source of anthropogenic sulfate into natural waters, mainly due to the extraction of metals from ubiquitous sulfur containing ores such as, pyrite and pyrrhotite. Because of its detrimental impact to freshwater species especially at high concentrations, its removal remains a priority in mine effluents. Future trends in regulatory practice may promote more research and application of sulfate removal technologies through desalination of mine water effluent. There are several strategies for mitigating sulfate removal. Among current options, ion exchange is very common. In this context, Aldex chemicals has developed a resin for sulphate removal in industrial water. Investigating other markets including mine sector is very challenging for the company. For this attempt, they tend to collaborate with the CTRI to demonstrate and validate the efficiency of their ion exchange technology for sulphate removal in mine effluents especially in cold climate. This project will benefit from a multidisciplinary team and an operational R&D infrastructure; essential ingredients for achieving the project's objectives within the given deadlines.
