Spatial and temporal variations in the Ruttan Mine tailings, Leaf Rapids, Manitoba, Canada

The Ruttan Cu-Zn mine produced approximately 30 million tons of fine-grained tailings over 30 years. Since the closure of the mine in 2002, the tailings have been systematically dewatered through trenches which drain into Ruttan Lake and into the open pit and underground mine workings. This study ev...
