· Compared with other beneficiation methods, gravity separation can be applied to a wide range of materials and has the advantages of low production cost and less harm to the environment. However, due to its low unit processing capacity and low recovery rate, we often adopt a combined process of strong magnetic separation and gravity separation.
The invention relates to the technical field of black metal ore exploitation and beneficiation, in particular to a beneficiation process of low-grade magnetite and specularite mixed ore, which is especially suitable for associated magnetite and specularite mixed ore of Zhouyoufang iron ore.

Low Grade Iron Ore Beneficiation In the past 50 years, due to high demand and intensive mining operations, the high grade deposits are depleting fast. By 2019-2020 it is estimated that the relatively low grade reserves are to be tapped. The importance of tailings can be understood by this proverb
The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster.
· As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed.
