Thallium content in lead-acid battery production
Abundance and fate of thallium and its stable isotopes in the ...
Except for acid mine drainage waters (discussed later), most lake and river waters show low levels of thallium in the 5–10 ng/L range (Peter and Viraraghavan 2005). Concentrations of Tl in stream waters of Europe vary from < 0.002 to 7.90 µg/L with a mean of 0.477 µg/L (n = 807) (Salminen et al. 2005).

Key facts about used lead-acid battery recycling | Reuters
The global lead-acid battery industry is worth about $65 billion annually, but when used batteries are recycled, the process has been identified as the most polluting in the world.
Thallium content in vegetables and derivation of threshold for safe ...
Thallium (Tl), as a dispersed metal element, is widely distributed and abundant in the earth''s crust and often coexists with sulfide ores of gold, iron, zinc, and lead due to its thiophilicity (Liu et al., 2019b). Generally, the Tl content is only 0.49 mg/kg in the continental crust (Wang et al., 2013).

However, lead dioxide (PbO 2) and lead sulfate (PbSO 4), which are main components of the lead-acid battery, are insoluble in the mentioned ILs. Hence, these IL-based processes use water-soluble lead salts such as lead nitrate or acetate, except that also water-insoluble lead carbonate was used in DIMCARB. [ 41 ]

Thallium
The production of thallium decreased by about 33% in the period from 1995 to 2009 – from about 15 metric tonnes to about 10 tonnes. Since there are several small deposits or ores with relatively high thallium content, it would be possible to increase the production if a new application, such as a thallium-containing high-temperature ...

automotive battery production equipment
The first practical version of a rechargeable lead-acid battery was invented in 1859. Of course, the technical requirements have changed enormously since then. We are all the more pleased that we have been supplying the lead-acid battery manufacturing sector with our production equipment for more than 50 years now.
