Fractionation of elements during copper smelting

Large enrichments, relative to crustal material, of many chalcophilic elements, e.g. arsenic, Se, Pb, Cd, Zn, tungsten and indium, have been reported for particulate material emitted from Cu smelters located in southeastern Arizona. There is also a significant difference in the enrichments for certa...

Description
Summary:Large enrichments, relative to crustal material, of many chalcophilic elements, e.g. arsenic, Se, Pb, Cd, Zn, tungsten and indium, have been reported for particulate material emitted from Cu smelters located in southeastern Arizona. There is also a significant difference in the enrichments for certain elements emitted from different Cu smelters. Results of a study of in-plant material collected at five Cu smelters in Arizona are reported. The samples were analyzed by instrumental neutron activation analysis and atomic absorption spectrometry for up to 35 elements. Large enrichments of the chalcophilic elements are due to their volatilization during Cu smelting. Variations in the elemental enrichments among the smelters appear to be due to differences in the feed material, smelting conditions and equipment used by the Cu smelters.13 refs.--AA
