Slurry disposal is a problem faced by many engineers dealing with mine tailings. In this paper, a study on the behaviour of a typical slurry is reported. When the slurry is very dilute, it undergoes particulate settling which is very slow. For treatment, it is desirable that the slurry undergoes hindered settling where the soil particles settle en-masse. When the soil partices settle and the water content of the slurry is reduced, it begins to gain in strength dramatically. This gain in strength may be small from a conventional soil mechanics view point but it can be used to treat the slurry. One way is to lay a thin layer of sand as a horizontal drainage layer on the slurry once it gains sufficient strength to arrest the settling of sand particles. Once this is feasible, a reclamation scheme whereby alternate layers of sediment and sand are constructed to reduce the drainage path of the fill can be considered.
