Current Status of Efficient Resource Utilization and Industrialization of Zinc Dust in Steel Plants
Steel smelting generates a large amount of zinc containing dust,among which blast furnace ash,electric furnace steelmaking dust and other zinc containing dust waste are seriously polluted and difficult to treat.Efficient and resourceful disposal of such lead and zinc solid waste resources can not only reduce environmental pollution,but also achieve the recycling of zinc and iron,meeting the requirements of green steel industry development.The utilization technology and industrial application of solid waste resources containing Zn are widely used,including the enrichment of ZnO through rotary kiln and rotary hearth furnace process,followed by chemical refining.Efficient and energy-saving resource utilization technology and equipment are the key to future industrial upgrading.
