Research Status and Development Trend of Zinc-Containing Solid Waste Recycling in Iron and Steel Plants |
| |
| Abstract: | The solid waste containing zinc such as blast furnace ash and electric furnace steelmaking dust produced by iron and steel plant was seriously polluted,and the treatment was difficult.Based on the introduction of zinc-containing ash output and its main components in iron and steel plants in China,this paper reviewed the current utilization technology of zinc-containing solid waste resources,and analyzed in detail the principle,process flow and existing problems of rotary kiln process,rotary hearth furnace process and wet process in pyro metallurgical reduction.The processes were compared from the aspects of raw material composition,main equipment and facilities,product situation,investment and environmental protection governance,and the development trend of utilization technology of zinc-containing solid waste resources in the future was suggested. |
