Cadmium and lead distribution in pyrite ores | Elementa

The pyrite ores are strategic industrial resources which generally serve as raw material for producing sulfuric acid. However, during the mining and industrial processing activities, associated toxic elements of cadmium (Cd) and lead (Pb) could be released into the surroundings, posing a significant threat to local environment and human health. In this study, the Institute for Reference

Thallium isotopic fractionation in industrial process of pyrite

02/15 · Such kinetic isotope fractionation may also explain the Tl isotopic fractionation during ore smelting/processing under high temperatures. As investigated by Vaněk et al. ( ) , the model volatile fractions have isotopically lighter Tl ( ε 205 Tl: –6.16 to –10.3) than the starting Tl-rich coal pyrite ( ε 205 Tl: –5.54) from a coal-fired power station.
