Graphite Ores Types and Mineral Processing and Purification …
Graphite with large flakes is naturally hydrophobic and has good floatability, so the flotation process can be used to recover the concentrate. However, graphite ore with smaller flakes, fine embedded particles and good taste requires a more complex beneficiation process. It can be seen that depending on the type of graphite ore, the …

22.4: Beneficiation
22.4: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue.

Flotation studies on low grade graphite ore from eastern India
A low grade graphite ore from eastern India was beneficiated by flotation to improve its quality. The ore was composed of 87.80% ash and 8.59% fixed carbon. Primary coarse wet grinding (d80: 186 μm) followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate.

Freeze-thaw weathering assisted beneficiation of graphite …
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).
