Static cylinder settling tests are a fundamental part of understanding slurry settling behaviour. Although the procedure is simple, the test provides valuable insights into slurry system surface chemistry and solid-liquid interaction, allowing optimisation of tailings dewatering.
Clear Insight into Settling Behaviour
The test allows engineers to directly observe how solids settle in a controlled environment. By marking the interface height at timed intervals, you can determine:
- Coagulant necessity
- Initial settling rate
- Flocculant performance under selected dosages
- Indicative bed concentration compaction under static conditions
- Supernatant clarity
- How particle characteristics influence settling behaviour
These observations help identify the most effective flocculant type for a given slurry and whether manipulating slurry system surface chemistry improves settling rates.
Essential Data for Thickening Design
The settling behaviour measured in this test supports several key engineering decisions:
- Coagulant and flocculant optimisation
- Thickener feed dilution for thickener feedwell design.
The static cylinder settling test is quick and uses little sample, so a wide range of parameters can be tested at low cost and little sample consumption.
