Evaporation is a phenomenon useful in assisting in the dewatering and stabilisation of
various mineral wastes. This paper summarises findings on the influence of cracking and …

Mineral slurries may be dewatered to the point that they manifest non-Newtonian behavior.
Many such slurries exhibit both thixotropic and hysteric behavior in their rheology, which has …

The slow settling of fine clays in oil sands residuals results in the generation of very large
amounts of fine tailings that must be stored in dammed impoundments. Dewaterability and …

Recent pilots on emerging oil sands tailings technologies have confirmed that deposit
thickness is an important parameter controlling tailings dewatering, and a key parameter …

The traditional Tempe cell can be used to adequately determine the soil water characteristic
curve (SWCC) for soils that do not undergo significant volume change as matric suction is …

In the oil sands industry, high temperature with the addition of a caustic dispersing agent has
formed the basis of the Clark hot water extraction process used successfully on a …

Amongst available technologies to the oil sands mining industry for processing fluid fine
tailings, centrifuge treatment technology has had some success at larger scales. In order to …

Consolidation in centrifuge cake tailings generated from bitumen extraction was studied in
experiments conducted in two phases. In phase I, 10 cm thick layers of centrifuged tailings …

Bottom seepage from oil sands tailings ponds into underlying strata may result in long term
environmental impact. Generally it is assumed that the tailings will consolidate at the bottom …

Reclamation of oil sands mines in northern Alberta presents a significant challenge for mine
operators, particularly the reclamation of tailings deposits that are produced by the mine …
