{{short description|Mixture of solids more dense than water suspended in liquid, usually water}}

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 micron[[micrometre]] up to hundreds of millimeters[[millimetres]].

:<math>\rho_{s}</math> is the solids density

:<math>\rho_{sl}</math> is the slurry density

:<math>\rho_{l}</math> is the liquid density

In aqueous slurries, as is common in mineral processing, the specific gravity of the species is typically used, and since <math>SG_{[[Relative density|specific gravity]] of water}</math> is taken to be 1, this relation is typically written:

even though specific gravity with units tonnes/m^³ (t/m^³) is used instead of the SI density unit, kg/m^³.
