Crushing must be done in order to release the flake from the enclosing country rock. Reduced ore is then feed to a mill where the ore is crushed further. Milling may be done in water slurry. At this point the individual flakes have been freed from the enclosing ore rock. The graphite/ore-rock slurry is then fed to froth floatation cells.

May 15, 2021 Artificial graphite spheroidization process Raw materials are uniformly sent to the CSM710 special mill single set series unit through the screw feed for ultra-fine grinding. Raw material particle size is milled to D5023-25m fine powder, which is convenient for the next process to be spheroidized.
Liberation The size and elemental analysis of mill feed shown in Table 1 indicate that there exists liberation of graphite around 150 micron size. The fixed carbon at 250 micron size fraction is around 13%, while at below 150 micron size it is above 15%.
Commercial flake graphite available for further grinding and processes is available in three primary sizes. These sizes are -100-mesh, 100-mesh, and 50-mesh. Depending on the source and requirements other more exotic cuts are available, but the above three are generally considered the work horses of the industry.
