Substance: Slimes and sludges battery scrap antimony and lead rich


“Slimes and sludges battery scrap antimony and lead rich are made by aqueous alkaline leaching of the majority of the sulphate from the lead-containing material recovered from recycled lead-acid batteries. The lead is mainly present as carbonates. Also other lead compounds, such as lead oxides, lead sulphate and lead silicate, and lead in metallic form may be present.”

EC number/ EINECS No.




Slimes and sludges battery scrab (Sb, Pb rich) is a brown, odourless solid (at 20°C and 101.3 kPA) in the form of sludge. The density will vary according to the precise composition of the sample. The density of the tested sample was 6.64 g/cm3. The melting point is shown to be > 500°C. Consequently, boiling point and vapour pressure cannot be determined. The water solubility test shows dissolution of metal ions. Two samples were tested for granulometry, a D50 = 39 micrometer and < 20 micrometer were determined. Both the results of the water solubility test and the granulometry test should be used with caution.


There is no evidence of physical hazards in terms of (auto)flammability, explosivity and oxidizing properties.

Studies regarding flash point, partition coefficient and surface tension do not need to be conducted.

Waivers are in place for all these endpoints.
