Applicant's summary and conclusion
- Conclusions:
- Good quality study that assessed full chemistry and mineralogy of two representative samples of lead dross copper rich/copper dross. 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 lead dross copper rich (or copper dross) samples (mixture toxicity rules).
- Executive summary:
The studied copper rich lead dross sample 09TT11158 consists mainly of metallic lead (56.7%) and galena (17.1%). Other notable mineral phases are lead copper sulphide (9.8%), lead antimony arsenic oxide (7.8%), tin lead sodium oxide (5.9%) and zinc oxides / hydroxides (1.4%). Chalcocite and copper arsenides occur as accessory minerals and copper is mainly carried by lead copper sulphide.
The studied copper rich lead dross sample 09TT11172 consists mainly of metallic lead and galena (total 47.4%), chalcocite (13.8%), copper and iron arsenides (total 12.7%) and tin-rich sorosite,Cu3Sn (12.4%). Other notable mineral phases include tin nickel antimony alloys (4.1%), tin sodium oxides (2.9%), sphalerite (2.3%) and silver tin (1.2%).
The studied copper rich lead dross sample 09TT08075 consists mainly of metallic lead (45.9%), galena (16.9%), pyrite (15.1%), chalcopyrite (7.7%), rosaite, PbSb2O6 (5.2%), chalcocite (4.5%), bornite (2.2%) and nickel antimony tin silver alloy. Lead is mainly carried by metallic lead. Rosaite is the main carrier of antimony in this sample. Pyrite carries most of the iron and sulphur of this sample.
The mineralogy of the reference samples can be used to derive the classification of both samples but also to predict the mineralogy of other lead dross copper rich (or copper dross) samples. The calculator sheet, which is used to derive the classification and which reflects particular assumptions that are made, can be found in attachment above (attached background material).
