One reason of this lack of information about Tl distribution in ore processing plants could be related to the fact that individual mines often do not want their Tl concentration published, as indicated by Peter and Viraraghavan (2005) We carried out preliminary analyses of waste dump leachates from a Pb–Zn–Cu ore processing plant in the Cerro de San Pedro mining district (San Luis Potosí, Mexico) This Special Issue welcomes contributions on thallium mineralogy, geochemistry, and ore geology, helping to describe the intriguing crystalchemistry of such a compound, its variable geochemistry, and to give further insights in the ore processes related to the formation of thalliumbearing ore deposits Dr Cristian BiagioniSpecial Issue "Thallium: Mineralogy, Geochemistry At the same time, total thallium in processing waste is significantly lower (071 μg g − 1) than in crude ore The major fraction obtained during sequential extraction is oxidizable thallium Crude ore contains approximately 50% oxidizable thallium, and all other fractions of the flotation process contain approximately 40–70%Translocation and mobility of thallium from zinc–lead

Thallium extraction process Metaleurop SA
A process for extracting and recovering thallium from a solution which contains said thallium in the form of salts of strong inorganic acids and salts selected from the group consisting of zinc, cadmium, nickel, cobalt, lead, bismuth and arsenic salts, wherein wherein said solution has a redox potential which is maintained at a reducing level, which process comprises a step of bringing the said solution into Thallium also is recovered as a byproduct from the flue dust and residues generated during the roasting and smelting steps in the processing of these ores Thallium metal and its compounds are consumed in a wide variety of applications; for example, thallium is used in semiconductor material for selenium rectifiers, in gamma radiation detection Thallium Statistics and Information USGSThallium contamination of the environment has been reported to be caused by coalburning power plants, emission from cement factories and water contamination by leaching of thallium from ore processing plants These can be readily absorbed through the skin Thallium is a potential human carcinogens [4] Isotopes of ThalliumThallium History, Uses, Facts, Physical Chemical
