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).

Applicant's summary and conclusion

Conclusions:
Good quality study that assessed full chemistry and mineralogy of two representative samples of lead dross antimony rich. 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 antimony rich samples (mixture toxicity rules).
Executive summary:

The studied antimony rich lead dross sample 09TT07598 consists mainly of lead antimony oxides (85.35%), metallic lead (8.65%) and antimony arsenic oxide and arsenic oxides (total 2.1%). The studied antimony rich lead dross sample 09TT11170 consists mainly of lead antimony oxides (92.3%), metallic lead (5.7%). The studied antimony rich lead dross sample 09TT07601 consists mainly of lead oxides (50.8%), lead antimony oxides (32.9%), lead antimony tin oxides (9%) and antimony lead calcium oxides (7%).

The mineralogy of the reference samples can be used to derive the classification of the samples but also to predict the mineralogy of other lead dross antimony 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).
