Beneficiation of Graphite
Beneficiation is any process which reduces the amount of unwanted ore or waste from the target metal or mineral which in this case is Graphite. At the lowest level this can be achieved by picking out lumps of raw material that looks high in Graphite or on a larger scale by not processing raw material thought to be low in Graphite.

On the other hand, the more valuable Sri Lankan lump graphite can reveal grades higher than 90% from hand sorting alone and before beneficiation. In addition to naturally occurring graphite, there are several processed graphite products including expanded graphite. Expanded graphite is made by treating the flake with chromic and sulfuric acids.
Ore Beneficiation
This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products. Low-grade hematite ores need to be upgraded to achieve the required iron content, which involves more complicated ore beneficiation processes. The level of comminution required for the low-grade hematite ore is ...

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].

Freeze-thaw weathering assisted beneficiation of graphite …
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). The main purpose of this strategy is to progressively liberate and remove the gangues from graphite concentrates, thereby minimizing the detrimental damage to ...
