SLURRY DENSITY
SLURRY DENSITY
(OP)
I would like to know if it is possible for a tailings slurry's density to change from the plant, to the deposition at the tailings dam.
The pipes come from the plant which is almost 30km away and goes through a series of diameter changes, also it splits into several directions (T-pieces)several times. Would it be possible for these splits and long distances to effect or change the final density of the slurry??
What could be some factors that effect a change in density for the slurry?

Does the density increase or decrease?

For concrete, there is a lot going on during pumping, so I doubt there is a reasonable comparison. Concrete viscosity changes with time, without regard to changes in density.

The exception to the above is the tee pieces- they may result in preferential splitting of solid/liquid fractions resulting in lower density at one location and higher at another.
Also please be aware that getting a representative sample of slurry lines is notoriously difficult. The finer the slurry, the better mixed (e.g. directly after a pump) and the thicker it is- the easier it is to get a representative sample.
As a chem eng/metallurgist the first part of any answer I give starts with "It Depends"
