Tailings
Mining dams pose a substantial risk, and residue management clearly needs to change. Alfa Laval is leading that transformation. The robust design and large capacity of our solid-bowl decanter centrifuges have proven the perfect solution for safe and secure dewatering of mine tailings. The small footprint substantially reduces installation space. The consistency of the solids fraction is perfect for co-disposal or dry stacking. And you recover large volumes of water for reuse.
Ensuring a fast, continuous process for safe, clean and efficient solid-liquid separation
- High capacity and separation efficiency with optimal solids dryness
- Long working life
- Designed for high-density sludge
- Compact design and small installation area
- Easy to scale-up capacities from test results
How the technology works
Alfa Laval P2 and P3 decanter centrifuges are specifically designed to separate mineral ore slurries as well as tailings into solid phase and liquid phase. Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The feed slurry enters into the bowl through a stationary inlet tube and is then smoothly accelerated in the feed zone. Centrifugal forces of up to 3,500 G separate the solid particles from the liquid and the solids accumulate on the inner surface of the bowl.
The conveyor rotates in the same direction as the bowl, but at a different speed. This gives an axial thrust to the solid particles and the conveyor conveys those particles towards the conical end of the bowl. The solids leave the bowl through the solids discharge openings into the casing whereas the clarified liquid leaves the bowl by flowing over adjustable plate dams or power tubes into the casing.
