| 摘 要： | 以煤粉作还原剂, 采用焙烧-浸出-磁选工艺对某铜渣中的铁进行了回收实验研究。探讨了焙烧温度、焙烧时间、煤粉用量、碳酸钠用量等因素对铁回收的影响, 最佳工艺条件为: 焙烧温度800 ℃, 焙烧时间60 min, 煤粉用量1%, 碳酸钠用量10%, 在此条件下获得的焙砂经进一步稀酸浸出和磁选, 可获得铁品位62.53%、铁回收率70.82%的铁精矿。

| Abstract: | With coal dust as reductant, recovery of iron from some copper-slag with the process of roasting-leaching-magnetic separation was tested, with the effects of roasting time and temperature, dosage of coal dust and sodium carbonate on the iron recovery investigated. The optimum condition was obtained as follows: roasting temperature of 800 ℃, roasting time of 60 minutes, dosage of coal dust and sodium carbonate of 1% and 10%, respectively. The calcine obtained was further subjected to the process of dilute acid leaching and magnetic separation, resulting in an iron concentrate grading 62.53% Fe at 70.82% recovery. |
