Abstract:The feasibility of roasting reduction method to dezinc the Zn bearing BF dust was proved by energy spectrum analysis and differential thermal(DT) and thermo gravimetric(TG) analysis firstly. Then optimal parameters of roasting reduction method with a dezincing rate up to 99.76% were determined by orthogonal method. The roasting temperature is 1200 ℃, the roasting time of 35 min and the coal content is 10%.
