近年来研究开发的褐铁矿选矿技术主要包括：重选、磁选等单一流程和选择性絮凝浮选等联合流程。
Beneficiation techniques on limonite developed in recent years mainly include single process of gravity or magnetic separation etc. and combined processes with selective flocculation flotation etc.
结果表明，采用选择性絮凝脱泥-阳离子反浮选流程闭路试验可获得铁精矿品位为65.50%，回收率为83.09%的较好指标。
The results showed that, an iron concentrate with a TFe grade of 65.50% and a recovery of 83.09% can be obtained by the closed-circuit bench test.
