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'.Tailings management in today's perspective is unable to sustain in the future. An effective end of the mine strategy needs a vision that goes beyond environmentally safe practice. At , our goal is to transform tailings management by changing legacy and risk prone practices with a .
