  • Iron Ore Processing Explained

    Limonite is rich in crystal water and has a low theoretical grade. Therefore, it is difficult for the iron concentrate grade to reach 60% by using physical beneficiation methods. The single separation process of limonite ore mainly includes gravity separation, magnetic separation, and flotation (positive and reverse flotation).
