摘　　要：通过能谱、差热及热重分析等验证了用还原焙烧的方法脱除高炉含锌粉尘中锌的可行性。用正交试验设计方法得到了最佳工艺条件:焙烧温度1 200℃,焙烧时间35 min,煤粉的添加量为10%。脱锌率可达到99.76%。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 1 200 ℃, the roasting time of 35 min and the coal content is 10% .
