Umicore Precious Metals Refining offers valuable recovery services to the zinc industry. Typically, primary the zinc industry is concentrating their valuable ‘minor-metals’ such as Ag, Pb and Cu into saleable by-products. These by-products from the zinc industry are globally sourced by Umicore to recover the valuable metals.
Typical products from the zinc industry are:
- leadsulphate: a product containing important amounts of Pb and Ag
- copper cement: acting as the outlet for Cu from a Zn-refinery flowsheet
- silver concentrate: this material can be generated to valorise the Ag contained in a Zn-plant
- drosses and skimmings: originating from the remelting of anodes in a Zn-plant
