Minerallum Engineering Tools

Slurry Density & Solids Calculator

Calculate slurry density, solid and liquid fractions, and derived flows from your values using a two-phase solid-liquid model without gas.

Mixture inputs

Use the particle/dry-solids density corresponding to the actual solid volume. Do not use loose or tapped bulk density.

Enter the actual carrier-liquid density for the relevant conditions. If dissolved species are present, use a liquid density that accounts for them.
