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).

Results and discussion
- Results:
- The studied lead antimonial dross sample 09TT11159 contains 75.3% lead, 6% Na2O, 4.2% zinc, 2.9% antimony and traces of other elements. The studied lead antimonial dross sample 09TT11159 consists mainly of metallic lead (57.4%) and lead sodium antimony oxide (31.2%). Other notable mineral phases are antimony sodium zinc oxide (5.2%) and zincite (+other zinc oxides / hydroxides, 4.3%). Lead silicate, oxides and anglesite, PbSO4, occurred as accessory mineral phases. This characteristic feature of this sample is coarse metallic lead grains. Complex particles are mainly mixing of different oxides including PbNaSb- and SbNaZn- and Zn oxides. The chemical composition of these three oxide phases varies greatly.

Applicant's summary and conclusion
- Conclusions:
- Good quality study that assessed full chemistry and mineralogy of one representative samples of lead antimonial 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 antimonial dross samples (mixture toxicity rules).
- Executive summary:
The studied lead antimonial dross sample 09TT11159 contains 75.3% lead, 6% Na2O, 4.2% zinc, 2.9% antimony and traces of other elements. The studied lead antimonial dross sample 09TT11159 consists mainly of metallic lead (57.4%) and lead sodium antimony oxide (31.2%). Other notable mineral phases are antimony sodium zinc oxide (5.2%) and zincite (+other zinc oxides / hydroxides, 4.3%). Lead silicate, oxides and anglesite, PbSO4, occurred as accessory mineral phases.
The mineralogy of the reference sample can be used to derive the classification of the sample but also to predict the mineralogy of other lead antimonial 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).
