  • Tailingsfo Dry Stacking of tailings

    IntroductionBauxite ResidueDatabase of Dry Stack Facilities in OperationDewatering tailings to higher degrees than paste produces a filtered wet (saturated) and dry (unsaturated) cake that can no longer be transported by pipeline due to its low moisture content. 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 1Live Chat
