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.

A method of pipelining iron ore permits transporting a range of particle sizes in the slurry through the use of relatively small concentration additives like chemical dispersant and viscosity control additives. Many stiff pastes, made up of finely ground solid material with enough liquid to saturate the voids, have both a yield stress and a ...
