IBP1037 09 SLURRY PIPELINE DESIGN APPROACH
Slurry characteristics definition can be performed in 2 phases. The first phase is by laboratory testing where a representative sample of the slurry is prepared at different concentrations. From this test, the slurry particle size distribution and rheology are obtained (see Figure 5). The result of this test is sufficient to produce an engineering

CSIRO: Understanding Slurry is Key to Good Tailings Pipeline …
On the other hand, a dilute slurry, such as iron ore tailings, has a lower viscosity and therefore needs to be pumped at higher velocity to reduce settling. Pumping at higher velocity has a downside though. It increases the velocity of solid particles hitting the walls of the pipe which in turn increases wear on the pipe walls.

Slurry rheology and tailings pumping design
In the example of the iron ore mine in the Pilbarra, slurry flow at approximately 40 weight % solids follows a Newtonian slurry calculation, and when the slurry is thickened to the target concentration of 50 weight % solids, the slurry has a significantly higher viscosity. A photo of the installed pipeline is shown in Fig 6.
