| 摘 要： | 河北某铁矿为含铁29.57%的低品位铁矿。为开发利用该矿产资源,进行了详细的选矿工艺研究。针对该铁矿主要是由磁铁矿和赤铁矿组成,并且与脉石矿物嵌布粒度较细的特点,最终采用弱磁-强磁-反浮选联合流程,获得含铁65.17%,回收率69.35%的铁精矿。

| Abstract: | A low-grade iron ore contains Fe 29.57% in Hebei.In order to exploit the resources,detailed mineral processing technology experiments are done.The iron ore is made up of magnetite and hematite,whose dissemination size is fine with gangue minerals.The combined flowsheet of low-intensity magnetic separation-high-intensity magnetic separation-reverse flotation is adopted.The final iron concentrate contains Fe 65.17% with recovey 69.35%. |
