摘要
对矿石结构构造、矿石化学成分和物相分析、矿物成分和赋存形式、矿物粒度及磁性等的研究,认为铁主要以磁铁矿形式存在,磁铁矿中的铁占82.38%,脉石矿物具有较弱的磁性。在矿石获得较充分解离条件下,采用磁选工艺能较好的将铁与脉石矿物及有害杂质分离,其磨矿细度是决定选矿回收率的重要因素。
On ore texture and structure, Chemical composition, phase analysis ,mineral composition and occurrence of, mineral grain size and magnetic studies ,Thought that it primarily existed in magnetite form, magnetite iron 82.38%, gangue minerals are weak magnetism.Ores dissociation conditions obtain full, Using magnetic separation process can better separate the iron from gangue minerals and harmful impurities, the grinding fineness is important factor determining recovery.
