GRAPHITE – Leading Edge Materials Corp

Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes ("buckyballs"). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss.

Natural Graphite — CarbonScape

Graphite ores are classified as "amorphous" (microcrystalline), and "crystalline" ("flake" or "lump or chip") based on the ore's crystallinity, grain-size, and morphology. All graphite deposits mined today formed from metamorphism of carbonaceous sedimentary rocks, and the ore type is determined by the geologic setting.

Is graphite amorphous or crystalline? - Quora

Aphanitic graphite crystal is very small, it is also called microcrystalline graphite, graphite particles are often embedded in the clay, and the separation is very difficult. As the ore grade is high (usually 60% to 80% carbon), so many of the graphite ore owner crush the ore stone and sell graphite powder directly.

Vein graphite is formed by fluid deposition, i.e. the transformation of oil precursors. The second discernible type of macro-crystalline graphite is so-called "flake graphite". This material is found disseminated in metamorphosed silica-rich quartzites, gneisses and marbles. The graphite content in the raw ore can vary from 5 to 40%.
