Zn and Pb smelters are the major contributors to Zn and Pb emissions among all
anthropogenic sources, thus, it is essential to understand Zn isotopic variations within the
context of metallurgical industries, as well as its fractionation in different environments
impacted by smelting activities. This mini review outlines the current state of knowledge on
Zn isotopic fractionation during the high-temperature roasting process in Zn and Pb
refineries; δ 66 Zn values variations in air emissions, slags and effluents from the smelters in …
