Characteristics of lead smelting fume and its potential treatment technology

Abstract Fine particles emitted from lead smelting furnaces contains a variety of heavy metals and oxidized condensates, which are characterized by complex composition and great harm. In this paper, dust samples from lead smelter were collected, and particle size analysis, composition analysis, phase analysis and specific resistance test were carried out in the laboratory. According to the properties of the lead dust, the experiment flow of electric coagulation was designed to verify the effect of using electric coagulation to condense fine particles in lead dust.
