The increasing demand for high grade graphite products with up to 99.99% carbon has led to develop various methods to remove impurities even to ppm range. This paper considers separation and purification techniques that are currently employed for graphite mineral beneficiation and identifies areas in need of further research.
And a series of study work on crystalline graphite beneficiation has been done by Chinese researchers [5-8]. Crystalline flake graphite has high natural hydrophobicity and usually is treated by flotation. But the traditional “grinding - flotation†process diminishes the lateral size of flakes seriously. Liu [9] used the â ...

However, the beneficiation of graphite ore is pivotal as it accounts for the quality, market price and suitability for various technological applications including energy storage in lithium-ion batteries. Since graphite is spontaneously hydrophobic (like coal) in nature, flotation is the common and apt technique for beneficiation of graphite ore.
Purification of microcrystalline graphite concentrate with alkali-acid leaching process was studied in this paper. The influences of alkali leaching temperature, NaOH concentration, alkali leaching time, HCl consumption, liquid-solid ratio, and acid leaching times were investigated respectively. Final refined products with carbon content in the …

Flotation has become the accepted method of beneficiation of graphite (Crawford and Ralston, 2008). Flake graphite from disseminated deposits is difficult to concentrate, therefore, a number of processes have been evolved by different countries. It has been found difficult to recover refined graphite from rough concentrate.
