Trace Element Study at a Primary Copper Smelter. Volume I.

摘要

The report presents the results of a project undertaken to explore the distribution of trace elements in environmental emissions from a primary copper smelter. The efforts were concentrated on the reverberatory furnace and the electrostatic precipitator controlling emissions from the reverberatory furnace. The following major conclusions were reached: (1) the electrostatic precipitator effectively controls all particulate emissions at its design efficiency rating (about 96%) at the operating gas temperature of 600degrees F; (2) appreciable material composed of toxic trace elements pass through the precipitator in the vapor state at the ESP operating temperature and condense to form particulate upon cooling. Arsenic trioxide was a major constituent of the emissions passing the ESP from the reverberatory furnace. The following elements were examined:Al,As,Ba,Be,Ca,Cd,Cr,Cu, F,Fe,Hg,Mo,Ni,Pb,Sb,Se,Si, V,Zn.
