Metso Outotec will deliver sustainable filtration technology for dry stacking of tailings to Eldorado Gold’s Hellas Gold Skouries copper-gold concentrator project in northern Greece.

Metso Outotec’s scope of delivery consists of the engineering, manufacturing and supply of several Planet Positive Larox® FFP3512 filters as well as installation and commissioning advisory services. The fully automatic, fast-opening filter press (FFP) combines the benefits of membrane technology and sidebar design with high mechanical and process performance, providing safe and sustainable high-volume dewatering of tailings at low operating and life cycle costs.

“Skouries is a world-class project, and we are aiming for best-in-class sustainable technologies in the project design. For tailings management, the Skouries project will use dry stack tailings impoundment, which requires less space, reduces water consumption and maximizes recovery of process water for reuse. Metso Outotec filters were selected as key and proven technology for the dry tailings facility not only because of their performance, but also because of their energy-efficiency,” says Brock Gill, SVP Projects & Transformation for Eldorado Gold.

“Eldorado Gold and Hellas Gold were looking for a reliable partner to help ensure the safety and sustainability of the Skouries tailings dry stacking facility. We are pleased having been chosen to deliver this core technology for the project. Previously, we’ve supplied proprietary technologies for grinding, flotation, thickening and automation to Skouries,” says Jussi Venäläinen, Vice President, Filtration business line at Metso Outotec.

The value of the order is approximately EUR 14 million, and it was booked in Minerals’ second-quarter orders received.

Metso Outotec’s filtration product portfolio is the largest in the field, and the energy, emission and water efficiency is in a league of its own. Metso Outotec has carried out over 14,000 filtration tests and delivered more than 5,000 filters for various applications worldwide. Metso Outotec also provides all filtration-related service and spare parts needs through its global service network.
