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 [13,14].Web
