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
