Coal slurry is a mixture of solids and liquids produced by a coal preparation plant.
A 2014 coal slurry spill into a river at Patriot Coal, West Virginia. A straw impoundment has been created across the river to try to hold the spillage.
A slurry is a mixture of denser solids suspended in liquid, usually water. The most common use of slurry is as a means of transporting solids or separating minerals, the liquid being a carrier that is pumped on a device such as a centrifugal pump. The size of solid particles may vary from 1 micrometre up to hundreds of millimetres.
The particles may settle below a certain transport velocity and the mixture can behave like a Newtonian or non-Newtonian fluid. Depending on the mixture, the slurry may be abrasive and/or corrosive.
