The physical separation (also known as beneficiation) typically involves several processes, such as mining, comminution, and flotation (Chelgani et al., 2016). In particular for graphite beneficiation, a multistage grinding and flotation process (can be up to 10 or more stages) is commonly employed (Peng et al., 2017, Peng et al., 2023).

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 ...
