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
Safe and Sustainable Tailings Management using Solid Bowl Centrifuge
Alfa Laval Mining & Minerals Industry Manager, Amol Chinchankar, discuss several alternative technologies for treatment and dewatering of tailings, and evaluate their productivity, risk management and environmental impact.
Breaking new ground in mining and minerals
Alfa Laval’s solid-bowl decanter centrifuges are the perfect choice for a wide range of solid-liquid separation duties in mining and mineral applications. They can replace or complement existing solutions and help boost capacity, reduce tailings volumes, save space and increase the recovery of water, chemicals and minerals. Above all, the decanter eliminates the need for tailing damns which enhance the intrinsic safety of your operation.
Optimizing your solid-liquid separation processes is a straightforward way to cut operating and investment costs while minimizing your company’s environmental impact. In many cases you can raise plant profitability by simply adding Alfa Laval’s solid-bowl decanter centrifuges to traditional separation systems such as thickeners, sedimentation basins, filters, etc, or replace the old system altogether.
