Mining and Mineral Processing Slurry Density Monitoring

Explore non-nuclear density measurement duties across grinding, classification, flotation, thickening and tailings.

Discuss your application

Choose the mineral-processing duty before choosing the measurement point

Mining circuits contain many possible slurry lines, but only a representative, fully understood stream can produce useful density data. Use this library to compare the process objective, hydraulic conditions, validation evidence and application limits for each duty.

Each guide explains the measurement objective, evidence, limits and next steps before an analyser is selected. For clay-processing duties, read our china clay and kaolin slurry density guide.

Grinding circuit density

Review mill, regrind and cyclone-classification measurement points.

Open grinding guide

Hydrocyclone feed

Plan density measurement for classification stability and circuit balance.

Flotation feed density

Connect pulp density to feed stability and mass-balance evidence.

Open flotation guide

Thickener underflow

Review underflow density, pumping and downstream filtration context.

Open thickener guide

Tailings monitoring

Separate thickening, filtration and transport-pipeline duties.

Build a defensible measurement plan

Use the same engineering sequence across every application.

Define the process

Map the material route, operating states and downstream decision.

Define the measurand

Choose density, concentration, COD equivalent or another stated output.

Collect evidence

Document range, composition, hydraulics, samples and process events.

Validate before use

Commission across the range and define invalid-signal handling.

Sources and application boundary

These sources define the general measurement context. Final suitability depends on the actual composition, operating range, pipe or vessel conditions, materials, installation point and validation evidence.
