Umicore Precious Metals Refining offers its PM-refining services to many copper smelters worldwide.
Typically Umicore can process:
- anode slimes, a complex combination of precious metals and impurities as Sb, Bi, As, Sn
- flue dust containing precious metals. This product typically originates from processes treating anode slimes
- PM-containing (doré) slags originating from the pyrometallurgical processing of anode slimes
- PM-containing residues originating from the hydrometallurgical treatment of anode slimes or from refining processes further down the flow of PM-refining
All these products are processed at Umicore using its unique capabilities to refine these complex products guaranteeing excellent recoveries of the precious metals.
