Breaking new ground in mining and minerals

Alfa Laval 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.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 decanter centrifuges to traditional separation systems such as thickeners, sedimentation dams and various filters, or replace the old system altogether.

Mature fine tailings, Canada

More than 30 Alfa Laval decanter centrifuges have been installed at three different tailings treatment sites in Canada. The decanters have proven to be an outstandingly efficient solution for large-scale dewatering of tailings. The decanters efficiently remove the finest particles that conventional solids control equipment is unable to deal with.

Eti Maden, Turkey

The world’s largest borate mining company, Eti Maden in Turkey, uses an array of fully protected Alfa Laval decanter centrifuges to separate tailings from a saturated borate solution. The company is very pleased with the long track record of reliable operation, low maintenance costs and strong local service support from Alfa Laval.
