Abstract: The current situation of pollutant generation and emission as well as its treatment of antimony industry in China was systematically investigated. The level of water pollution and the status existing problems of control techniques were analyzed. The research showed that the treatment level of the mining wastewater of antimony industry was low and the fluctuation of the wastewater flow and quality was vast. When the wastewater was not pre-treated, the concentration of the emission into the tailing dam was as high as 11.92 mg/L. The wastewater from smelting process was mainly smelt slag wastewater mixed with cooling water and domestic sewage in small factory. In the smelting process, there were other problems, e.g. sulfur dioxide emission from blast furnaces not reaching national standard, heavy metals in the flue gas having not effectively treated, and arsenic and alkali slag being stockpiled in open-air mode, etc. It was suggested that the cleaner production audits should be strengthened and management on the various wastewaters be enforced to improve the water recycling rate and the comprehensive use of arsenic residue and waste ore.
