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).
