内蒙古某铁矿石选矿试验研究

为了高效开发利用内蒙古某铁矿石资源，在矿石工艺矿物学性质研究的基础上开展了

高压辊磨—湿式磁选抛尾—塔磨—磁选全流程试验研究。结果表明：原矿经高压辊磨制得-1 mm粒

级粉矿，在400 mT磁场条件下湿式磁选抛尾，获得了全铁品位36.63%、磁性铁品位为31.31%的湿式

预选精矿，湿式预选精矿经塔磨磨至-0.030 mm占95%，经1粗1精磁选获得了铁品位为65.78%、回收

率为66.22%的铁精矿，试验结果可以为该铁矿石选别流程确定提供依据。

In order to efficiently develop and utilize an iron ore resource in Inner Mongolia，on the ba⁃

sis of the study of the mineralogical properties of ore technology，the whole process of high-pressure roller

grinding，wet magnetic separation，tail throwing，tower mill and magnetic separation was carried out. The

results show that the - 1 mm particle size fine ore was obtained by the high-pressure roller grinding ma⁃

chine，and the wet pre-separation concentrate with a total iron grade of 36.63% and a magnetic iron grade of

31.31% was obtained under the condition of 400 mT，and the wet pre-separation concentrate tower was

ground to -0.030 mm accounting for 95%，and the iron concentrate with an iron grade of 65.78% and a re⁃

covery rate of 66.22% was obtained by one roughing and one cleaning magnetic separation，and the test re⁃

sults could provide a feasible process for the iron ore separation.
