摘要: 针对山东金岭铁矿选矿厂尾矿中含有少量强磁性铁矿物的实际情况,研究了从尾矿中选铁的工艺方法。结果表明,在尾矿铁品位为3.70%的情况下,采用一粗一精弱磁选—磁选柱再选工艺流程,可获得精矿铁品位为45.87%,铁回收率为5.21%的分选指标。

Abstract: In light of the fact that there is small amount of strongly magnetic iron-bearing minerals in the tailings of Jinling Iron Concentrator, the process for recovering the iron from the tailings was studied. As a result, a process consisting of one roughing and one cleaning by low intensity magnetic separation and re-concentration by magnetic separation column was adopted, which obtained an iron concentrate having a grade of 45.87% and a recovery of 5.21% from tailings containing 3.70% iron.
