• Copper smelting is a significant source of SO 2 emission. It is important to quantify SO 2 emissions from combustion sources for regulatory and control purposes in relation to air quality. The characteristics of SO 2 emissions from copper smelting industry in Yunnan Province, China, were examined. Analysis based on the present situation, material balance and measuring method were used to confirm SO 2 emission factors of copper smelting industry. Results show that SO 2 emission factors for Isa system, side blown-continuous converting system (SB-CC), blast furnace-continuous converting systems (B-CC) and blast furnace-converter blowing (B-C) are 11.69–18.64, 62.44–101.4, 19.43–37.88 and 45.48–81.03 kg/t(blister copper), respectively. The comprehensive emission factor based on all smelting plants is found to be in the range of 23–39.99 kg-SO 2 /t(blister copper) for Yunnan Province, China. The results are compared with those for discharge coefficients of industrial pollutants in the First National General Survey of Pollution Sources and the emission factor of the total amount of major pollutants. It is observed that there are some differences among emission factors.
