摘　　要：介绍了旋流-静态微泡浮选柱加脉冲磁场后的设备结构与工作原理,对比进行了磁铁矿的浮选柱工艺反浮选试验及加脉冲磁场后的浮选柱工艺反浮选试验。研究表明,相比浮选柱工艺,加脉冲磁场后,在浮选精矿、尾矿产品质量及回收率均有提高的情况下,新设备的处理能力提高了45.83%,并简化了工艺流程。The structure and working principle of cyclonic-static micro-bubble flotation column with an additional pulsed magnetic field were introduced.The tests of magnetite reverse flotation process by using cyclonic-static micro-bubble flotation column without and with an additional pulsed magnetic were done and compared respectively.Studies showed that after adding pulsed magnetic,the processing capacity of the device was raised by 45.83%,and the quality of concentrate and tailings and iron recovery were improved also,besides,the technological flow-sheet was simplified obviously.
