2017 Workshop

This year’s topics were tailings modification and mitigation, drainage treatment and prediction of drainage chemistry with a focus on new developments in Ontario and Quebec. The workshop consisted of twenty-four presentations and included issues at mine sites in Sweden, United States and across Canada.
