Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
For classification purposes, the classification of the UVCB is based on the hazard of the constituents. This has been determined following CLP mixture toxicity rules using the MeClas tool.
For risk assessment purposes, the assessment covers the risks posed to all relevant environmental compartments by releases of selected environmental driving constituents during the production and use of the refinable substances. Exposure assessment has been undertaken separately for each of the driving constituents. These are arsenic, cadmium, chromium, copper, lead, nickel, silver and zinc. The refinable substances have variable composition and may not contain all of the environmentally hazardous constituents so the generic exposure assessment for each refinable substance only considers the relevant constituents.
Conclusion on classification
The environmental classification for this substance has been derived using the MeCLAS tool. The classifications for Slags, precious metal refining, are grouped classifications based on the composition profiles. This approach has been used for Slags, precious metal refining, as it consists of a small and relatively uniform (yet still sufficiently variable to be considered a UVCB) group, where a number of composition profiles are expected to be manufactured and/or imported.
Notes:
· For the speciation used for classification, please refer to the table in CSR Section 3.0.3.
· Classification drivers are (worst case) assumptions and do not necessarily represent real species/mineralogical composition.
There are two different grades of Slags, precious metal refining, and the environmental classification for each grade is presented below.
Slags, precious metal refining 1 (Slags, precious metal refining, doré production)
The MeCLAS tool has been used to derive the classification for Slags, precious metal refining, doré production on the basis of its composition, showing that it would be classified for the environment under CLP as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410).
Slags, precious metal refining 2 (Slags, precious metal refining, production of precious metal containing materials other than doré)
The MeCLAS tool has been used to derive the classification for Slags, precious metal refining, production of precioua metal containing materials other that doré on the basis of its composition, showing that it would be classified for the environment under CLP as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
