WebNov 18, 2013 · 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. On the other hand, lump graphite grades at least 89% Cg and sometimes 99% pure graphite. WebGraphite has a metallic appearance and black color that may initially be confused with magnetite, but the two are easily distinguished by their other properties. Magnetite is …
