Flocculation and Sedimentation of Dispersed Particulate Systems: Recent Developments

摘要

The properties and characteristics of discharged tailings material can be traced, not only to the source material variations, but also to the many complex processes brought to bear, from conditioning, digestion, and separation stages in the extraction of product material. The complex interactions established between the various constituents in the tailings material discharged, can be evaluated in terms of specific suspension volumes--which express the amount of water held by each specific constituent in the tailings. Furthermore, the subsequent dynamics of the material--settling, dehydration and crusting--can be better assessed if the mechanisms which promote interaction between the constituents are better understood. The suspension volume concept provides the first step towards this direction.
