MMC Norilsk Nickel

Residue, nickel matte leaching is defined as:

Product obtained by leaching Nickel matte with chlorine or sulphuric acid.  It is composed primarily of copper sulphide and sulphates

The Joint Registration dossier was successfully submitted to ECHA on 24th September 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, the 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 Residue, nickel matte leaching 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):

Residue, nickel matte leaching
