Research on Comprehensive Recycling of Blast Furnace Dusts

In this article,based on analysis on properties of blast furnace dusts in Tangshan,a process for comprehensive recycling of blast furnace dusts is put forward and validated through a range of tests.The results show that in the process,blast furnace dusts including Fe and C can be effectively recycled,and non-ferrous metals such as K,Na,Pb,and Zn can also be separated and collected through multistage hydrometallurgical process,which realizes the comprehensive utilization of blast furnace dusts. The researches prove that it is the best way to utilize blast furnace dusts.
