In this paper, the possible chemical reactions of lead, zinc and arsenic in the process of oxygen-enriched side-blown bath smelting in copper smelting were sorted out. The distribution and trend of lead, zinc and arsenic in smelting slag, matte, flue gas and soot were studied, and the final product forms of lead, zinc and arsenic were determined. In view of the white soot produced in the process of pyrometallurgical copper smelting, the present situation of its comprehensive utilization was summarized, and the development trend of comprehensive utilization of white soot resources was put forward.
