Improved Flotation of Fine Flake Graphite Using a Modified
Natural graphite ore can be easily purified by froth flotation due to its natural hydrophobicity [3,4,5,6]. Flake graphite exhibits a stronger hydrophobicity and is more floatable than amorphous graphite [7,8,9,10,11,12]. As illustrated in Figure 1, graphite beneficiation generally consists of a multistage grinding and flotation process A novel and simple flotation technique has been developed to prepare high-purity graphite from impure graphite.

Towards sustainable extraction of technology materials through Nature
Natural graphite is mined by open-pit and underground methods, followed by beneficiation. To reach a 90–98% purity requires acid and/or alkali leaching of the gangue material to remove silicateBased on the data obtained from the preliminary analysis of the natural crystalline flake graphite in Table 1, Table 2, we determined the type of reagents (acids) that are useful for the purification process of graphite.In general, silica (61.68 % in Table 2) as the major impurity could be effectively reduced by utilizing both HF and a caustic soda Chemical purification processes of the natural crystalline flake

Purification, application and current market trend of natural graphite
In beneficiation of graphite by the method of flotation, it has been almost impossible to avoid the entrainment of gangues such as sericite into graphite concentrate. Hence, to solve the aforementioned problem, the use of Nigrosin (C 22 H 16 N 6 O 3 ) as a depressant for graphite in lead-zinc ore processing technology was introduced recently Graphite beneficiation and Extraction Method Stone.
