Slimes and sludges, copper electrolytic are defined as :

A complex combination of insoluble compounds produced by precipitation during the copper electrolytic refining or winning processes.  It consists typically of various metals (such as precious metals, copper, antimony, tin, selenium, tellurium, arsenic, lead and nickel), as well as their oxides and/or sulphates.

The Joint Registration dossier was successfully submitted to ECHA on 23rd August 2010.  Members of the ECI-managed Consortium, along with any purchasers of the appropriate Letter of Access, were provided with the necessary documents, plus the required REACH IT security token.

In April 2014, this joint dossier was extended to satisfy REACH Art.10 conditions, including the provision of a joint Chemical Safety Report (CSR).

The substance is used solely as Intermediate.

Depending on their own manufacturing and use profiles, individual members of this joint registration may have decided to register the substance in accordance with Strictly Controlled Conditions (SCC) requirements (REACH Art. 17/18), or as a full registration (REACH Art 10). Letter of Access purchasers are requested to contact ECI should they wish to upgrade their own registration from Art 17/18 to Art 10 and to secure the rights to use the Joint CSR.

ECI’s REACH Classification, Labelling and Packaging proposals for Slimes and Sludges, copper electrolytic have been assessed in the REACH dossier in accordance with Regulation (EC) 1907/2006 and the CLP Regulation (EC) 1272/2008. The rationales for these proposals are contained in the Joint Submission dossier submitted to ECHA by the Lead Registrant.

The 2014 conclusions below reflect the latest Adaptation to Technical Progress (ATP):
