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 slimes and sludges battery scrap Sb Pb 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 slimes and sludges battery scrap Sb Pb rich samples (mixture toxicity rules).
Executive summary:

The studied sample 10TT03302 consists mainly of cerussite, PbCO3 (58.9%). Other notable mineral phases include metallic lead and lead oxides (tot. 21.8%), anglesite, PbSO4 (12%), lead silicate (5.1%) and sodium calcium silicate (2.2%). The studied sample 10TT00905 consists mainly of cerussite, PbCO3 (61.5%). Other notable mineral phases include metallic lead and lead oxides (tot. 24.5%), lead silicate (6%), anglesite PbSO4 (6%), sodium lead carbonate hydroxide (2.2%), and lead antimony oxide (0.75%).

The mineralogy of the reference samples can be used to derive the classification of both samples but also to predict the mineralogy of other slimes and sludges battery scrap Sb Pb rich 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).
