Applicant's summary and conclusion
- Conclusions:
- Good quality study that assessed full chemistry and mineralogy of two representative samples of flue dust lead refining/flue dust blast furnace. 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 flue dust lead refining (or flue dust blast furnace) samples (mixture toxicity rules).
- Executive summary:
The studied Flue dust, sample 09TT09775 consists mainly of Zn-bearing natrojarosite (51%), anglesite (20.4%) and metallic lead (14.8%). Other notable mineral phases are lead antimony-, lead zinc- and lead tin oxides (total 5.4%), zincite (5.1%) and zinc sodium- & lead silicate hydrates (total 2.2%).
The studied Flue dust, sample 09TT08073 consists mainly of fine-grained cotunnite, PbCl2 (48.7%), anhydrite (44.5%) and anglesite (6.9%).
The mineralogy of the reference samples can be used to derive the classification of both samples but also to predict the mineralogy of other flue dust lead refining (or flue dust blast furnace) 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 sulphur content. 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).
