2. WEEE: Sexy? Well, it all depends on your taste. Electronic scrap is a complex mix of many different substances:Cu, Ag, Au, Pd,

3. 3 The value of circuit boards varies significantly high grade: Au > 400 g/t
medium grade Au 200 - 400 g/t
low grade Au 100 - 200 g/t
very low grade Au < 100 g/t
4. 4 A sophisticated & accurate sampling process is needed to determine the true metal content Experience and integrity of the precious metals refiner is crucial for reliable assays
5. 5
6. 6 Metals refining is a complex metallurgical “disintegration” and separation process
7. 7 There is more room for optimisation by considering the entire WEEE recycling chain
8. 8 Optimising the trade-off between preprocessing & smelting/refining
9. 9 Much more than PCB-recycling: From a commodity to customised solutions Our integrated metals refinery can treat:
populated and unpopulated circuit boards
entire small devices after battery removal (e.g. mobile phones, handheld computers etc.)
Plastic fractions with (precious) metals
Cu- or Fe-based metallic fractions (with/without PM)
Components like IC‘s, MLCC, hard disks, contacts, ...
...
Within Umicore we also recover Li-ion and NiMH batteries
10. 10 We are committed to eco-efficient recycling
11. 11 Focus on eco-efficiency - finding the right balance between ecological and economical performance
12. 12 By-products from smelters and refiners
Industrial & consumer recyclable products
Precious Metals
Base Metals
Special Metals
Chemicals
Aggregate for concrete Example: the Umicore smelter & refinery at Hoboken/Antwerp (Belgium)
