Abstract | This project was 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 600 degrees 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. |
