CAS number: 67711-91-5
Product of smelting roaster calcines concentrates or cement copper with flux in reverberatory or electric furnaces. Composed primarily of copper and copper, iron and lead sulfides with minor sulfides of other metals.
According to MeClas, the
substance is not classified.
The study provided a conservative estimate, derived on basis of the classification outcome (mixture toxicity rules) from a reasonable worst-case sample of the substance using mineralogical information from the representative sample.
Validity of the model used:
1. Defined endpoint: the endpoint is a REACH compliant defined endpoint
2. Unambiguous algorithm: EU CLP guidance based summation formula to determine classification, followed by back-calculation to related hazard criteria
3. Applicability domain: applicable to classify complex metal containing materials.
4. Mechanistic interpretation - metal species: the tool translates the elemental composition into a mineralogical composition relevant for classification.
