Thanks to its unique metallurgical flowsheet, Umicore Precious Metals Refining processes a broad range of complex precious metals, lead, copper and nickel bearing materials from a variety of worldwide sources.
Umicore Precious Metals Refining is one of the world's major processors of by-products from the non-ferrous industry. Among others, these industrial by-products include: dross, PM-containing slag, matte, flue dust, hydrometallurgical residue, filter cake, tankhouse slimes and copper cement.
Umicore Precious Metals Refining has the capability to comply with new sources of precious metals bearing materials. We process by-products from:
Umicore Precious Metals Refining has the capability to process complex concentrates while guaranteeing excellent recoveries on payable metals such as Ag, Au, Cu and Pb.
Among others we process:
- complex concentrates that contain a combination of elements that would be difficult to process by conventional means. Any combination of Pb, Cu, Ag and Au combined with impurity levels that go beyond conventional boundaries, can be processed.
- Pb-concentrates with high levels of precious metals
- Pb-concentrates with high impurity levels
- by-products from mining operations such as:
- gold on carbon
- precious metal residues
