| 摘 要： | 某铁矿为微细粒弱磁性铁矿，有用矿物主要是赤铁矿和磁铁矿，脉石矿物主要是石英．在磨矿中产生许多矿泥，影响其可浮性．采用重选、磁选、浮选、选择性絮凝和磁化焙烧等工艺处理该矿石．结果表明，采用选择性絮凝脱除矿泥，阳离子反浮选工艺最合适．在原矿含铁45．27％的情况下，获得铁品位59．67％，回收率78．84％的铁精矿．

| Abstract: | An iron ore belongs to micro-fine and refractory one, in which the usable minerals are hematite and magnetite with quartz as gangue mineral. Flotability is impacted by slurry out of the grinding process. Process tests are performed respectively on the iron ore including gravity separation, magnetic separation, flotation, selective flocculation and magnetizing roast. The results show that des-liming by selective flocculation, and reverse flotation through positive ion collector is the most optimized process. Iron concentrate with the grade of 59.67 % and the recoverv rate of 78.84 % is obtained out of iron ore containinz rate of 45.27 %. |
