Understanding High-Grade Lump Graphite

2013-11-18 · In contrast, lump graphite is basically formed as a solid, nearly pure mass. One way to see this is in the typical ore grades in a graphite deposit. Flake graphite ore typically grades 2—3% Cg (total carbon in graphite form) but can range up to 10—12% Cg. Amorphous graphite deposits might even be as high as 12–17% Cg.

Graphite

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.
