A majority of the studied graphite had a distinctly flakey (0.2–1 mm in length) or platy morphology with a well-ordered crystal lattice. Beneficiation studies were performed to produce high-purity graphite concentrate, where rod milling and froth flotation produced a final concentrate of 90% fixed carbon with recoveries between 67% and 83%.

Graphite ore crushing. (1) Raw ore feeding particle size: 300~500mm; (2) Final product particle size: 10~20mm; (3) The commonly used crushing process is a two-stage open circuit or a three-stage open circuit; (4) The equipment is a jaw crusher for primary crushing, a cone crusher, or a hammer crusher for final crushing.

The development of small flakes inside the rock is the result of regional metamorphism. Lump graphite is created when hydrothermal activity changes the carbon compounds inside the rock. Description. Most prevalent, carbon quality: 20%–40% (low) Good abundance, carbon grade <90%. Carbon grade >90%, rarest in supply. Major producers.

Natural graphite is mainly found in three types: crystalline flake, microcrystalline or amorphous, and crystalline vein or lump [1]. Due to the parallel …
