Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The tested representative sample was characterized (physico-chemical and mineralogical properties) in view of the upcoming REACH registrations of copper intermediates and copper slags by the Copper Consortium.
The studied representative speiss sample contains 55.9% copper, 10.2% antimony, 7.35% arsenic, 7% nickel, 0.12% lead and 2.4% sulphur. The studied speiss sample consists mainly of metallic copper (32.4%), covellite, CuS, (26.2%), iron arsenic -alloy, FeAs (17.5%), nickel antimony –alloy, NiSb, (14.9%) with accessory copper arsenides and copper- tin alloys.
Metallic copper carries 51.3% of the speiss total copper content, and covellite carries (34%). The rest is carried by copper and iron arsenides and copper- tin alloys. The main carrier of arsenic is iron- arsenic –alloy (72%), other carries being metallic copper and copper arsenide. The lead in the studied sample occurs as metallic.
None of these constituents is known to show explosive properties

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.
