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.

Graphite is texturally-variable within and across units. Crystal habit varies from highly crystalline to irregular flakes. Flake sizes range from amorphous and crystalline small flake to coarse large flake (> 150 µm), with beneficiation of ~ 70% and yield potential of > 95% (froth flotation methods).

Graphite ore is extracted by underground and open cast mining. Beneficiation takes place by sorting according to carbon content, crushing and enrichment. The lump graphite found in Sri Lankan deposits is the purest natural graphite known, with a carbon content of up to . Such high purity is not required for many applications.

Graphite beneficiation and Extraction Method | Stone. 23-01-2012· Generally the naturally occurring graphite is of low grade, so it is not suitable for industrial applications. Froth flotation is commonly used for the concentration of low grade graphite ore. There are mainly there beneficiation method to extracted the high grade graphite ...

The flake size distribution significantly affects the value of graphite products. The graphite grain size distribution was determined using the thin section identification method based on the polarized optical microscope with the lump graphite sample described above. The results are shown in Table 2.A total of 69.50% graphite particles were in the 75–10 μm size fraction.
