How a simple thickener maintenance request evolved into a productivity enhancement project
At an Australian mine, we delivered a first-of-a-kind feedwell upgrade to an existing tailings thickener, substantially reducing operating costs and improving water sustainability.

Application | Tailings Thickener Feedwell Upgrade |
Study type | Customer Story |
Country | Australia |
The custom-designed E-Volute™ feedwell with E-DUC® autodilution mechanism replaced an old bifurcated feedwell that had been supplied in the 1990s. We also provided onsite engineering support to ensure this complex project was completed smoothly. As a result of the work:
- Flocculant consumption has fallen 27%
- Underflow density has increased 2% w/w
- Water to tailings has fallen 6%
Overall, payback was achieved in ten months. The new feedwell has also helped the mine reduce its raw water draw by helping to increase reuse of mine affected process water.
