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.
