Aurubis has decided an investment of EUR 70 million in the construction of a state-of-the-art and energy-efficient bleed treatment facility at its Olen site. In a hydrometallurgical process, BOB will recover valuable metals such as nickel and copper contained in electrolyte streams that are generated in the tankhouses of the metal production at the Aurubis sites in Beerse and Olen in Belgium. The installation comprises a complete tankhouse purification system that is known as bleed treatmentAs a high-performance metal recycling site in the Aurubis smelter network, the plant in Olen processes, besides blister copper, up to 135,000 tons of multimetal recycling materials annually and produces copper cathodes via electro refinery as well as Aurubis Rod, Foxrod, and Bars and Profiles. The plant in Beerse processes more than 250,000 tons of complex recycling materials and operates a copper tankhouse. BOB is an important addition to the Belgian production cluster to extract nickel and copper from material flows as well as to remove impurities from the bleed.Detailed engineering and approval processes for BOB are currently underway. The start of construction for the facility is planned for September 2022. Commissioning of BOB is planned for summer 2024.Aurubis AG is a leading global provider of non-ferrous metals and one of the largest copper recyclers worldwide.
