iron ore beneficiation magnetic separation quality planning

  • Developments in the physical separation of iron ore

    The ore is mainly composed of magnetite, hematite, martite, and quartz It is very difficult to produce a highquality iron ore concentrate by magnetic separation alone for this type of iron ore The ore is first ground using ball mills down to about 90% 75 μmThe choosing of iron separation equipment depends on specific ore natures and magnetite iron ore is usually concentrated by magnetic separation, but what about the beneficiation of hematite, limonite, specularite? TheIron Ore Jigging Separation Processing PlantAn implementation of twostep concentration (afterpurification) allowed increasing the iron content in the concentrate up to 482% It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase (socalled, wet separation) Fig 5 shows the iron ore after the process of magnetic separationDry Magnetic Separation of Iron Ore of the Bakchar
