01 Iron ore tailings classification. Iron ore tailings can be divided into magnetite tailings and hematite tailings according to the mineral properties of the raw ore. Due to the large displacement of magnetite, its production output is three times that of hematite, so the displacement of magnetite tailings is greater than that of hematite tailings. . The yield ratio of …
