Amorphous Graphite

About Amorphous Graphite

It is a mineral with a black metallic luster that looks like earth or a lump of earth, and is non-crystalline Graphite that resembles anthracite, but has a dull luster and a low volatile.  However, it is difficult to distinguish from anthracite in appearance alone.  The condition of vein is a pocket deposit which is very similar to that of manganese ore, and it is generally mined by underground methods.  Raw ore is mainly hand sorted to remove gangue, that is refined to a grade of 80% or more and then imported.  If high-quality products are required, wet flotation is repeated in Japan to remove ash.  However, it is difficult to float since the shape is not flaky compared to Vein Graphite, resulting in a lower yield and becomes expensive.  Amorphous Graphite is inferior to Vein Graphite in various respects except that it is black in color and easily micronized, but it is used in an extremely wide range of applications because it is inexpensive.
