ore beneficiation graphite

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 [13,14].

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 …
