Abstract

Abstract

In this study, the formation and properties of sintering dust with various hazardous element (i.e. K, Na, Cl, Zn, etc.), blast furnace dust and converter dust in iron and steel enterprises were investigated. The laboratory research on the comprehensive utilization of the three kinds of precipitator dust and the production technology at home and abroad were summarized. The dechlorination process of sintering dust and blast furnace dust was emphasized. The technology of zinc extraction by rotary kiln from blast furnace dust and converter dust was also emphatically introduced. So that, the improvement measures were put forward according to the difficulties faced in the production process. Through cost and benefit analysis the dechlorination process by hydrometallurgy method and zinc extraction by rotary kiln from precipitator dust were recommended to iron and steel enterprises.
