Increasing the integrated use of iron ore raw materials is associated with an increase in the yield of iron concentrate and the production of hematite concentrate during the beneficiation of ...

Current industrial practice of processing of iron ore fines in India does not involve much beneficiation. However, few plants in India are treating fines during washing, classification, and jigging process [4]. In other parts of the world, iron ore fines are beneficiated for magnetite- and hematite-rich iron ore in * P. Dixit prashant.dixit ...

The hematite ore in China is characteristic of low grade, fine-grained and non-homogenous distribution particles. Most of the ores are liberated only under the precondition that the production particle size distribution (PSD, % <74 μm) is within the range of 70–90%.Therefore, the two or more closed-circuit grinding processes in sequence are scheduled in the hematite …

The invention discloses a beneficiation method capable of being appliable to hungry hematite and belongs to the technical field of beneficiation.
