Substance: Wastes lead battery reprocessing

 

“Wastes, lead battery reprocessing is made by recovering the lead compounds from exhausted lead-acid batteries and converting it into a prepared solid feed suitable for lead smelting. Lead is mainly present as oxides, sulphates and in metallic form.”

EC number/ EINECS No.

CAS No.

305-445-7

94551-99-2

Wastes, lead battery processing is a sienna/brown odourless solid (at 20°C and 101.3 kPA) in the form of a paste. The density will vary according to the precise composition of the sample. The density of the tested sample was 6.78 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. Regarding granulometry a D50 = 41 micrometer was 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.
