For cold climates, dry stacking prevents pipe freezes and frosting problems with conventional impoundments. Groundwater contamination through seepage is virtually eliminated. Filtered tailings allow better recovery of dissolved metals and process chemicals e.g. gold and cyanide.
A large copper concentrator with a tailings output of 100,000 tonnes per day, for example, could save 200 million m3 of water over ten years by using our dry stacked tailingsbining thickener and filter with our RAHCO® mobile stacking and conveying system to dispose of the tailings as dry filter cake, states Todd Wisdom.

An increasing number of aluminum refineries are converting the traditional tailings ponds into filter press cake dry stacking. This trend is favored by a series of advantages, such as reduced risk of external dam wall failure and, consequently, red mud spill, lower environmental footprint and higher soda recovery.
The dry stacking plant using filter presses offered the shortest delivery time. Delivery of the equipment required precise coordination with the limited access period afforded by the ice road. In this case, the tailings consists of a thickened slurry with a solids fractionposed of quartz.
In the face of recent high profile tailings dam failures there has been an increased focus on the consideration of tailings filtration and dry stacking systems as an alternative to conventional or thickened discharge based tailings management systems.
