Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 266-967-8 | 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.
Endpoint summary
Administrative data
Description of key information
- complex metal containing substance
- solubility of metal constituents is poor
- bio-accessibility in gastric fluids and sweat
- particle size distribution and relevance of “respirable fraction”
- classification via mixture toxicity rules
Key value for chemical safety assessment
Additional information
The UVCB substance is a complex metal containing substance. Each individual (metal) constituent of this UVCB substance can release soluble ions that can contribute (as ‘relevant’ component) to the mixture toxicity. With knowledge of the elemental composition (IUCLID section 1.4 & 1.2) and mineralogical information on the Grade representative sample (IUCLID Section 4.23), the mixture toxicity rules (EU CLP Guidance Annex I: 3.9.3.4, and cut-off) was used to calculate the Classification of the UVCB substance.
Chemistry and mineralogy of the material (see IUCLID section 4.23 chemical and mineralogical characterization) were taken into account.
Justification for classification or non-classification
Specific Target Organ Toxicity (repeated): not classified
The classification derived is applicable to Grade 1 Copper matte
Specific Target Organ Toxicity (repeated): Category 2 H373 (oral)
The classification derived is applicable to Grade 2 Copper matte
See end-records and discussion above for detailed justifications
The tested sample was representative for typical across industry (each Grade), defined within the concentration ranges outlined under IUCLID section 1.2
