Abstract: A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for slurried waste and dredged material. Syncrude Canada Ltd. is considering changing the nature of its tailings to material which consolidates more rapidly and can be disposed of in a smaller storage area. Properties and behaviour are used as an example. Boundaries between sedimentation and consolidation states, segregating and non-segregating mixtures, and fluid and solid states are shown.
