摘　　要：采用还原焙烧工艺对内蒙黄岗高锡铁精矿的处理进行了研究,考察了主要工艺参数对脱锡效果的影响。最佳试验条件下,焙烧后球团矿含铁67%,含锡、锌均小于0.01%,锡挥发率大于98%,锌挥发率大于96%,球团抗压强度大于170kg/个,0.5m落下强度大于50次。还原焙烧工艺是处理高锡、锌铁精矿行之有效的方法。Experimental research on the treatment of Sn-bearing iron concentrates for tin removal were performed by reductive roasting.Under optimum conditions the contents of iron,in the pellets of roasted iron concentrate were about 67%,with the zinc and tin contents both less than 0.01%.The volatilization rate of Sn was more than 98% and that of zinc was more than 96%.The comprehensive strength of the pellet was more than 170kg,and the falling strength at 0.5 meter high was more than 50 times.Reductive roasting is an effective solution to treating the iron concentrate with high contents of Sn and Zn.
