Large-Scale WEEE Recycling Integrated in an Ore-Based Cu,
Feb 01, 2018· At Boliden’s Rönnskär smelter, WEEE is smelted in a Kaldo process and the black copper, together or without the slag, is charged to the PS converter. This process route has proven to be a viable way to obtain a high WEEE smelting capacity in an originally ore-based process system. Experience shows that the slag in the PS converter is usually not fully liquid, and the amount of solids,Recycling Technology - Aurubis,Apart from copper, these materials are used to produce by-products such as precious metals, nickel, tin, lead and zinc. 1.
