Blowing in the wind Monitoring dust from legacy mine tailings to keep communities safe SASKATOON – Queen's university researchers have studied dust blown from legacy mine tailings at the Giant Mine in Yellowknife, NWT and determined vital information to inform future remediation efforts. Using the CLS@APS, the researchers were able to determine the chemical form of arsenic in dust particles sourced from the Giant Mine tailings which intermittently blow into nearby communities. "The synchrotron is really useful for looking at dust because you have this really tiny micron scale beam that you can focus on individual dust particles and get...
