Test material

Constituent 1
Reference substance name:
Flue dust, copper-refining
EC Number:
266-966-2
EC Name:
Flue dust, copper-refining
Cas Number:
67711-90-4
IUPAC Name:
flue dust, copper refining
Details on test material:
Sample collection made according to ECI/REACH Copper Consortium Standards Protocols (see IUCLID section 1.4)
The studied flue dust samples are fine- grained, the D50 value is for all samples below 20µm. They contain 9.18- 51.0% lead, 0.52- 9.58% copper, 6.3- 43.9% zinc, 0.09- 2.8% arsenic, and 1.15- 14.7% sulfur (see iuclid 4.23)
B11 flue dust from Secondary smelters (representative), sample code: MC_B11_522_xxx_0904, lab code: 09TT03192
B11 flue dust from primary smelter (blast furnace) (dried filtered slime, homogenized), sample code: KGHM_B11_006_0904, lab code: 09TT03514
B11 flue dust from primary smelter (electric furnace) (composite, from one silo), sample code: KGHM_B11_005_0904, lab code: 09TT03513

Results and discussion

Applicant's summary and conclusion

Conclusions:
Good quality data that show that representative samples for the UVCB flue dust are mainly present in powder forms
Executive summary:

Major fraction of the materials is smaller than 20µm (inhalable fraction). This has to be taken into account for classification.
