Flake type graphite occurs as flat, plate-like crystals, with angular, rounded or irregular edges, with the crystals disseminated throughout originally carbonaceous metasediments.
Flake graphite ranges in flake size from 1mm to 25mm, with an average size of 2.5mm. For commercial purposes, flake graphite is divided into coarse flake (150-850µm in diameter) and fine flake (45-150µm in diameter).
Fine flake may be further subdivided into powder (-75µm), fine flake (75-100 µm) and medium flake (100-150µm). Impurities include minerals that are commonly found in metasediments – usually quartz, feldspar, mica, amphibole, garnet and calcite, with occasional amphiboles, pyrrhotite, pyrite and magnetite.
Natural Graphite's brief Introduction
Graphite is an industrial mineral with unique physical properties which includes superior thermal/electrical conductivity and generally occurs in one of three forms – Microcrystalline or amorphous, Crystalline lump or vein and Crystalline flake.
Natural Flake Graphite occurs in host rocks such as quartz-mica schist, feldspathic or micaceous quartzite and gneiss. Flake graphite may also occur in metamorphosed carbonate rocks, though these occurrences are currently of little economic significance. Flake graphite deposits are usually strata bound, with individual beds or lenses ranging from 30cm to more than 30m thick, and extending for lengths of two kilometres or more. Ore bodies are normally tabular, occasionally lenticular, and occur locally as irregular bodies in the hinge zones of folds. Most economic deposits of flake graphite are of Archean to late Proterozoic age.
