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 three representative samples of slags lead smelting. 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 slags lead smelting samples (mixture toxicity rules).
- Executive summary:
The studied slag sample 09TT07600 consists mainly of Ca-silicates; merwinite / bredigite (29.0%) and amphibole-type silicate (24.0%). Other notable mineral phases are iron oxides (20.7%), metallic lead (11.2%), sulphides (6.8%), zinc iron oxides (5.7%) and magnetite (2.4%). Metallic lead is the main lead carrier (98.5%) in this sample. Iron is mainly carried by iron oxides (59%).
The studied slag sample 09TT08045 consists mainly of mainly of hardystonite (34.5%), other Ca-silicates (19.6%), iron oxides (13.8%), fayalite (9.9%), chabazite (5.2%) and magnetite (5.2%). Metallic lead is the main lead carrier and sorosite carries most of the copper in this sample.
The studied slag sample 09TT07596 consists mainly of fayalite (49.6%) and other silicates (38.0%). Other notable mineral phases are troilite (4.5%), iron sulphates, (4.0%) and FeCrNi –alloys (2.6%). Wüstite, metallic lead, sorosite and arsenides occur as accessory minerals.
The mineralogy of the reference samples can be used to derive the classification of these samples but also to predict the mineralogy of other slags lead smelting 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 form in which lead was maily present (compounds/metal). 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).
