Translocation and mobility of thallium from zinc–lead ores

Aug 01, 2021Thallium is a toxic, non-essential element. Zinc–lead ores are a known source of thallium pollution. The aim of this paper was to investigate the translocation of thallium from zinc–lead ores from the Cracow–Silesia Upland due to ore flotation processing and natural processes and the element's mobility in these samples as determined by sequential extraction in accordance with a

DETERMINATION OF GERMANIUM, GALLIUM, INDIUM AND THALLIUM

Jul 31, 2021Nowadays, due to using many rare metals in the most advanced technologies, the demand for these metals is increasing. Rare metals, however, mostly don't show the property of creating their own mineral deposits, making their production more complicated. Some rare metals, e.g. gallium, germanium, indium and thallium usually accompany zinc ore.

Thallium Test

Thallium is released by coal fire power plants, cement factories, and smelting operations, and can then deposit onto nearby soil and plants. This process is a common source of thallium exposoure. Individuals working in industries associated with thallium release regularly have higher levels of thallium due to deposition of thallium on their skin.

Method for the removal of thallium

A method for removing thallium ions from aqueous solutions uses manganese dioxide sludge produced during the electrolysis of zinc. The preferred allotropy of MnO 2 is the α-form, which selectively absorbs thallium ions with minimum interference from other elements and metal ions present in the solution, and is significantly more economical than other reagents currently used for the same purpose.
