These filtered tailings are normally transported by conveyor or truck, deposited, spread and compacted to form an unsaturated tailings deposit (Davies and Rice 2001). This type of tailings storage produces a stable deposit usually requiring no retention bunding and is referred to as dry stack. Figures 1 and 2 show the La Coipa dry sLive Chat
