MODELLING TURBULENT TRANSPORT OF SOLIDS IN NON-NEWTONIAN CARRIER FLUIDS APPLICABLE TO TAILINGS DISPOSAL
Original language description
The increased volume of thickened tailings being sent to tailings storage facilities has created a need to predict what the transport characteristics of these non-Newtonian suspensions are, and what pumping capabilities are required. For very fine particle disposal, where the particle size is less than 20?m e.g. red mud, the material may be considered to behave as a homogeneous fluid and conventional non-Newtonian fluid pipeline design techniques can be successfully employed. However, in many thickenedtailings, the size distribution is much wider than this, often containing sands that are added either before or after thickening. Where the concentration of the rheologically active particles are sufficiently high, such that the suspension may be considered to behave as a paste in laminar flow, then suitable non-Newtonian stratified flow models are used successfully to quantitatively model these flows. When the concentrations of the rheologically active particle are lower, such that the
