%X Artisanal zinc smelters using indigenous method have exited in Hezhang county, Guizhou province for more than one hundred years. However, the systemic and large-scale smelting works have lasted less than thirty years since the 80-90th last century. Most of mercury will emit to the atmosphere in the process of smelting according to the property of mercury. The concentration of mercury in ore, scoria, coal and slag were determined, the results showed the highly significant positive correlation coefficient between concentrations of mercury and zinc. Then, using mass balance, the mercury emission factor of sulfide ore and oxide ore were 155 gram mercury per ton zinc and 79 gram mercury per ton zinc through calculating respectively in the process of zinc smelting. The emission amount of mercury in the smelting process could be estimated. And the further study on environmental hazards of mercury to the local environment is called for.
