Background The flake graphite is the main raw material for producing the cathode material, and the micro-fine particle flake graphite in the prior art is used as one of graphite ore resources, and the granularity range of the flake graphite is mainly between 10 and 1 mu m. The graphite ore is particularly distributed in nature, and a series of challenges are faced in the beneficiation process due to the extremely fine and uniform embedded particle size of gangue minerals and graphite particles thereof. Traditional beneficiation methods, such as multi-stage grinding and flotation, are capable of processing most of the graphite ores, but are not attractive when facing micro-fine particle flake graphite. The core problem is that the dissociation of the micro-fine particle graphite and gangue minerals requires finer and energy-consuming ore grinding operation, which not only increases the energy consumption in the ore dressing process, but also prolongs the flotation process flow.
