Materials and methods
- Principles of method if other than guideline:
- Chemistry /elemental analysis was determined using ICP (inductively Coupled Plasma spectroscopy). Metal speciation/metal mineralogy was assessed from Sequential extraction/metal analysis and mineralogical analysis (XRD and microscopes equipped with EDS (Energy Dispersive Spectrometry) and WDS (Wavelength Dispersive Spectrometry) analysers. The interpretation of the overall results was performed by expert (with profound knowledge of metal particularities).

Results and discussion
- Results:
- The tested materials were characterized (physico-chemical and mineralogical properties) in view of the upcoming REACH registrations of copper intermediates and copper slags by the Copper Consortium.
Any other information on results incl. tables
The studied copper matte samples consists mainly of copper, 52.4- 77.3%Cu with 1.6%- 14.6%Fe, 0.04- 1.1%As, 0.05- 6.7%Pb and 18.9- 21.7% sulfur and they consist mainly of copper sulfides of chalcocite or bornite –types. The amount of copper sulfides ranges between 74.2- 96.4%. The rest of the matte samples consist of accessory phases like copper arsenides, metallic copper, magnetite and copper oxides of cuprite –type.
In every case, copper sulfides carry most 83- 95.9% of mattes total copper content, rest being carried by metallic copper, copper arsenides, cuprite and magnetite. When encountered, arsenic is carried either copper arsenides or it occurs as trace element in copper sulfides and metallic copper. In most cases, lead is carried by metallic lead, one by galena –type lead sulfide and one by both metallic lead (84%) and lead oxides (16%)
The chemical analysis of studied sampled are given in Table 7 and Table 8 and their mineralogical composition in Table 9 and Table 10 with distribution of copper.

Applicant's summary and conclusion
- Conclusions:
- Good quality study that assessed full chemistry and mineralogy of several representative Copper matte samples. Proposed RWC mineralogy (distribution pattern for each key element, i.e. % from Total into the various mineralogical forms/species present into the UVCB) can be used for classification of the UVCB substance (mixture toxicity rules)
- Executive summary:
The tested materials were characterized (physico-chemical and mineralogical properties)inview of the upcoming REACH registrations of copper intermediates and copper slags by the Copper Consortium.
The studied copper mane samples consists mainly of copper, 52.4- 77.3%Cu with1.6°c- 14.6%Fe, 0.04- 1.1%As, 0.05- 6.7%Pb and 18.9- 21.7% sulfur and they consist mainly of copper sulfides of chalcocite or bornite —types. The amount of copper sulfides ranges between 74.2- 96.4%. The rest of the matte samples consist of accessory phases like copper arsenides, metallic copper, magnetite and copper oxides of cuprite—type.
Inevery case, copper suit ides carry most 83- 95.9% of mattes total copper content, rest being carried by metallic copper, copper arsenides, cuprite and magnetite. When encountered, arseniciscarried either copper arsenides oritoccurs as trace elementincopper sulfides and metallic copper.Inmost cases, lead is carried by metallic lead, one by galena—typelead sulfide and one by both metallic lead (84%) and lead oxides (16%)
Based on these results the following Distribution patterns can be derived (indicative, NOT relevant for classification):
Matte FF(eg from Flash furnace, or electric furnace):
Copper present in th form of Cu metal (16.5% from total Cu)+ sulphides (83.5%)
Lead in the form of Pb metal (100% from total Pb)
Nickel in the form of Ni metal (100% from total Ni)
other (minor) metal elements: if present, in the form of sulphide (each 100% from total element)
Matte WM(eg from white matte):
Copper present in th form of Cu oxide (WC Cu(I), 1.04% from total Cu)+ Cu metal (4.65% from total Cu)+sulphide (94.35% from total Cu)
Lead in the form of Pb sulphide (WC Pb compounds, 100% from total Pb)
Nickel in the form of Ni metal (100% from total Ni)
other (minor) metal elements: if present, in the form of sulphide (each 100% from total element)
Matte BF(eg from Blast furnace):
Copper present in th form of Cu oxide (WC Cu(I), 1.04% from total Cu) + Cu metal (16.86% from total Cu)+ sulphides (83.1% from total Cu)
Lead in the form of Pb oxide (WC Pb compounds, 16.04% from total Pb)+ metal (83.96% from total Pb)
Nickel in the form of Ni metal (100% from total Ni)
Cobalt in the form of sulphide (68.27% from total Co)+ metal/inclusion (31.73% from total Co)
other (minor) metal elements: if present, in the form of sulphide (WC, each 100% from total element)
Based on Transformation/dissolution results, and gastric bio elution results, knowledge on the release patterns showed that conservative Pb forms (eg Pb compounds) are to be preferred. The following compiled RWC Distribution pattern is therfore derived (relevant for classification):
This distribution pattern is conservative, in particular in respect Pb (assuming total Pb is soluble compound form) and is therefore a worst case applicable to all grades
Copper Matte (RWC):
Copper present in th form of Cu oxide (WC Cu(I), 1.04% from total Cu) + sulphides (94.35% from total Cu)
Lead in the form of Pb oxide (WC Pb compounds, 100% from total Pb)
Nickel in the form of Ni metal (100% from total Ni)
Cobalt (if present) in the form of sulphide (68.27% from total Co)+ metal/inclusion (31.73% from total Co)
other (minor) metal elements: if present, in the form of sulphide (WC, each 100% from total element)
