Tailingsfo Dry Stacking of tailings</h3>INTRODUCTIONBAUXITE RESIDUE (RED MUD)DATABASE OF DRY STACK FACILITIES IN OPERATION (IN DEVELOPMENT)Dewatering 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 1

Influence of dry density and water content on the swelling

of compacted bentonite have been investigated. Results on the influence of initial dry density and water content on the swelling pressure and swelling deformation of a compacted bentonite are presented. Swelling pressure is exponentially related to dry density but is rather independent of the initial water content of the clay.
