| A '''slurry''' is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with a liquid (usually water), often used as a convenient way of handling solids in bulk.<ref>Oxford English Dictionary 2nd ed.: Slurry</ref> Slurries behave in some ways like thick [[fluid]]s, flowing under gravity but are also capable of being [[pump]]ed if not too thick.

| ==Calculations==
| |
| | |
| ===Determining solids fraction===
| |
| To determine the percent solids (or solids fraction) of a slurry from the density of the slurry, solids and liquid<ref>Wills, B.A. and Napier-Munn, T.J, ''Wills' Mineral Processing Technology: an introduction to the practical aspects of ore treatment and mineral recovery, ISBN 978-0-7506-4450-1'', Seventh Edition (2006), Elsevier, Great Britain</ref>
| |
| :<math>\phi_{sl}=\frac{\rho_{s}(\rho_{sl} - \rho_{l})}{\rho_{sl}(\rho_{s} - \rho_{l})}</math>
| |
| where
| |
| :<math>\phi_{sl}</math> is the solids fraction of the slurry (state by volume)
| |
| :<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_{water}</math> is taken to be 1, this relation is typically written:
| |
| :<math>\phi_{sl}=\frac{\rho_{s}(\rho_{sl} - 1)}{\rho_{sl}(\rho_{s} - 1)}</math>
| |
| even though specific gravity with units tons/m^3 is used instead of the SI density unit, kg/m^3.
| |
| | |
| ===Liquid mass from mass fraction of solids===
| |
| To determine the mass of liquid in a sample given the mass of solids and the mass fraction:
| |
| By definition
| |
| :<math>\phi_{sl}=\frac{M_{s}}{M_{sl}}</math>*100
| |
| therefore
| |
| :<math>M_{sl}=\frac{M_{s}}{\phi_{sl}}</math>
| |
| and
| |
| :<math>M_{s}+M_{l}=\frac{M_{s}}{\phi_{sl}}</math>
| |
| then
| |
| :<math>M_{l}=\frac{M_{s}}{\phi_{sl}}-M_{s}</math>
| |
| and therefore
| |
| :<math>M_{l}=\frac{1-\phi_{sl}}{\phi_{sl}}M_{s}</math>
| |
| where
| |
| :<math>\phi_{sl}</math> is the solids fraction of the slurry
| |
| :<math>M_{s}</math> is the mass or mass flow of solids in the sample or stream | |
| :<math>M_{sl}</math> is the mass or mass flow of slurry in the sample or stream
| |
| :<math>M_{l}</math> is the mass or mass flow of liquid in the sample or stream
| |
| | |
| ===Volumetric fraction from mass fraction===
| |
| :<math>\phi_{sl,m}=\frac{M_{s}}{M_{sl}}</math>
| |
| Equivalently
| |
| :<math>\phi_{sl,v}=\frac{V_{s}}{V_{sl}}</math>
| |
| and in a minerals processing context where the specific gravity of the liquid (water) is taken to be one:
| |
| :<math>\phi_{sl,v}=\frac{\frac{M_{s}}{SG_{s}}}{\frac{M_{s}}{SG_{s}}+\frac{M_{l}}{1}}</math>
| |
| So
| |
| :<math>\phi_{sl,v}=\frac{M_{s}}{M_{s}+M_{l}SG_{s}}</math>
| |
| and
| |
| :<math>\phi_{sl,v}=\frac{1}{1+\frac{M_{l}SG_{s}}{M_{s}}}</math> | |
| Then combining with the first equation:
| |
| :<math>\phi_{sl,v}=\frac{1}{1+\frac{M_{l}SG_{s}}{\phi_{sl,m}M_{s}}\frac{M_{s}}{M_{s}+M_{l}}}</math>
| |
| So
| |
| :<math>\phi_{sl,v}=\frac{1}{1+\frac{SG_{s}}{\phi_{sl,m}}\frac{M_{l}}{M_{s}+M_{l}}}</math>
| |
| Then since
| |
| :<math>\phi_{sl,m}=\frac{M_{s}}{M_{s}+M_{l}}=1-\frac{M_{l}}{M_{s}+M_{l}}</math>
| |
| we conclude that
| |
| :<math>\phi_{sl,v}=\frac{1}{1+SG_{s}(\frac{1}{\phi_{sl,m}}-1)}</math>
| |
| | |
| where
| |
| :<math>\phi_{sl,v}</math> is the solids fraction of the slurry on a ''volumetric'' basis
| |
| :<math>\phi_{sl,m}</math> is the solids fraction of the slurry on a ''mass'' basis | |
| :<math>M_{s}</math> is the mass or mass flow of solids in the sample or stream
| |
| :<math>M_{sl}</math> is the mass or mass flow of slurry in the sample or stream
| |
| :<math>M_{l}</math> is the mass or mass flow of liquid in the sample or stream
| |
| :<math>SG_{s}</math> is the bulk specific gravity of the solids
