Applicant's summary and conclusion
- Conclusions:
- Good quality study that assessed full chemistry and mineralogy of three representative samples of matte lead/matte-copper lead. The mineralogy (and the distribution pattern for each key element, i.e. % from Total into the various mineralogical forms/species present into the UVCB) of the reference samples can be used to derive the classification of matte lead (or matte-copper lead) samples (mixture toxicity rules).
- Executive summary:
The studied lead matte, sample 09TT07597 consists mainly of troilite, FeS (42.8%), wüstite, FeO (18.7%), iron sulphates (17.1%), metallic lead (5.7%), metallic iron (5.5%) and delindeite, Ba-silicate (4%) The studied lead matte, sample 09TT07599 consists mainly of troilite, FeS (48%), iron sulphates (17.9%), wüstite, FeO (16.1%), fayalite (11.6%) and metallic lead (3.8%). The studied copper-lead matte, sample 09TT08043 consists mainly of galena, PbS (52%), chalcocite, Cu2S (27.5%) and lead oxide, PbO (15%). Lead silicate and other silicates, magnesium iron chromium oxides, antimony nickel –alloys, accessory minerals, copper lead sulphides, lead nickel oxides and iron zinc oxides.
The mineralogy of the reference samples can be used to derive the classification of these samples but also to predict the mineralogy of other matte lead (or matte-copper lead) samples. Differences in speciation between the reference samples, and anticipated differences in classification, initially suggested the need for two grades of this intermediate based on the form in which lead was maily present (compounds/metal). As a consequence, company specific classifications were calculated using one of the two different speciation patterns.The calculator sheets, which are used to derive the classification and which reflect particular assumptions that are made, can be found in attachment above (attached background material).
