Test material

Constituent 1
Reference substance name:
slag, copper smelting
EC Number:
266-968-3
Cas Number:
67711-92-6
IUPAC Name:
slag, copper smelting
Details on test material:
Copper slags are presented in the form of granules, massive(stones) or powder.
Partcle size distribution was determined on representatuive samples from the three different forms of slag. Samples were collected at different sites,
Granules: Samples 09TT02641, 09TT02988, 09TT03512, 09TT05246, 09TT02986, 09TT03177, 09TT03821
Stones: Samples 09TT05245, 09TT03503, 09TT03181
Powder/fines: Samples 09TT03989, 09TT02987

Sampling and sample preparation was performed according to ECI/REACH C1 Sampling Protocol. The C1 sampling protocol also provides detailed information on the identity of the samples (see IUCLID section 1.4).

Granules and powders were tested in their original partcile size as placed on the market. Stones were crushed to less than 5 mm before testing.

Applicant's summary and conclusion

Conclusions:
Copper slags are presented in the form of granules, massive(stones) or powder.

Partcle size distribution was determined for the three different forms of slag.

Granules and powders were tested in their original partcile size as placed on the market. Stones were crushed to less than 5 mm before testing

D50 of parcle size for the slag granules is measured in the range of 741 - 2426 µm
D50 of parcle size for the slag stones is measured in the range of 1316 - 2029 µm
D50 of parcle size for the slag fines is measured in the range of 30 - 70 µm
