Thallium has 25 isotopes which have atomic masses that range from 184 to 210. 203 Tl and 205 Tl are the only stable isotopes and make up nearly all of natural thallium. 204 Tl is the most stable radioisotope, with a half-life of 3.78 years. It is made by the neutron activation of stable thallium in a nuclear reactor.The most useful radioisotope, 201 Tl (half-life 73 hours), decays by electron ...

thallium was used in rodenticide and ant killer. Thallium is also used in photocells, glass manufacturing, the electronics industry, pharmaceutical products, and to treat skin infections. Potential sources of contamination in drinking water include leaching from ore-processing sites, discharge from electronics, glass, and drug factories.
This Special Issue welcomes contributions on thallium mineralogy, geochemistry, and ore geology, helping to describe the intriguing crystal-chemistry of such a compound, its variable geochemistry, and to give further insights in the ore processes related to the formation of thallium-bearing ore deposits.
Thallium is a rare metal, found in small quantities in some varieties of iron and copper pyrites, and in some lithia micas. It resembles lead in appearance. Its compounds resemble the salts of the alkalies in some respects; and, in others, those of the heavy metals. It is detected by the green colour which its salts impart to the flame. This, when examined with the spectroscope, shows only one ...

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...
Oct 26, 2016· In case of bottom sediments originating from small rivers (Sztoła, Baba, Biała Przemsza, Dąbrówka), which often receive discharge streams from zinc–lead ore mines (including the Pomarian ore mine) as well as the local zinc smelter and flow through exposed ore-rich dolomites, the content of thallium reached 12.9 to 23.5 mg kg −1.
Thallium 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 modified ...
Thallium is a highly toxic metal found in trace amounts in copper, lead, zinc and other ores. It's used in specialized electronic equipment, and can end up in drinking water through leeching from ore-processing sites and discharge from factories. Health Effects of Thallium. Thallium is toxic to the nervous, gastrointestinal, and respiratory ...

Sep 11, 2003· Thallium was determined in 120 samples of soil and 30 samples of stream sediments from the southeastern part of the Silesian-Cracowian zinc−lead ore deposits. Soil samples were taken from topsoils (0.0−0.2 m) and bottom soils (0.8 and 1.0 m). Thallium was determined by flow-injection−differential-pulse anodic stripping voltammetry. The samples were decomposed sequentially …
Ores are presently only mined for thallium in China [Zhang, et al, 1998]; i.e., Nanhua, Yunnan and Lanmuchang, Guizhou. The Nanhua property is an As-Tl containing thallium up to 0.19%.

The invention relates to a process for extracting thallium present especially in aqueous wastes of industrial origin. The process, which makes it possible to extract and recover thallium from a solution which contains it in the form of a salt of a strong inorganic acid, comprises a stage of bringing the said solution into contact with an ion exchange resin containing a thiol group.
Thallium (Tl) is typical rare element with severe toxicity comparable to Hg and Pb. To track Tl pollution, isotopic fractionation of Tl was evaluated during pyrite smelting for sulfuric acid production. Large variations in Tl isotope compositions were observed among the pyrite ore (PO) and its four different smelting wastes.
