| 摘 要： | 以转底炉工艺技术为基础,采用高温焙烧-磁选分离工艺对济钢高炉含锌粉尘脱锌富集铁进行了实验室研究,考察了还原温度、还原时间及配煤量对含锌粉尘脱锌率、金属化率、磁选精矿产率以及铁回收率的影响。实验结果表明最佳工艺参数为:还原温度1 350℃,还原时间30 min,配煤量4%。在此条件下的脱锌率和金属化率分别为99.75%和99.46%,精矿产率为45.63%,铁回收率为95.76%。

| Abstract: | Laboratory studies on dezincification and iron enrichment of zinc-bearing dust in Jigang by high temperature roasting-magnetic separation process were conducted based on the rotary hearth furnace technology.The effects of reduction temperature,reduction time and coal blending rate on dezincing rate of the zicn-bearing dust,metallization rate,yield of magnetic concentrate and iron recovery were investigated.The results showed that the optimum process parameters were that the reduction temperature was 1350 ℃,reduction time was 30 min and coal blending rate was 4%.Under these conditions,the dezincing rate and metallization rate were 99.75% and 99.46%,respectively,yield of the concentrates was 45.63% and iron recovery was 95.76%. |
