Tailings Dam

Robert Duda in Waste Management Series 2004V 5 7 Conclusion The presented prediction of contaminants migration in the area of the Zelazny Most flotation tailings dam indicates that only lowering of the groundwater table level close to the dam embankments resulting from vertical drainage by dewatering wells may limit propagation of contaminants in groundwater around the dam Get price
