There are 3 types of graphite in nature. These are called Amorphous Graphite, Flake Graphite and Vein Graphite. These names are given due to the appearance of graphites under the microscope. Amorphous graphite got this name because it is amorphous and lumpy due to its structure. Flake graphite has a layered structure and is closer to gray in color. Core graphite is the most valuable of these three types and has the highest carbon value that can be obtained without processing.
The term amorph actually does not have much place today. All graphite types differ according to the crystal density they contain. Amorphous natural graphite has a microcrystalline structure. Therefore, it would be more correct to say “microcrystalline graphite or cryptocrystalline graphite”. Its density is 2-2.2 gr / ml. It can be found at 60% -85% carbon purity from underground, or if the reserve is close to the surface, mining operations can be continued with the open pit method.
The mineralization occurring in the Oysu region is of micro crystalline and macro crystalline graphite type. More precisely, the metamorphism of this series within a crystalline mass of an old coal level eventually occurred. Graphite in the mine deposit is a single type ore.
Materials with a grade of 65% to 90% carbon can be produced from the ore that can be enriched by the flotation method. In addition to being conductive, it is a slippery and chemically stable material. This allows it to be used in many different sectors.
Microcrystalline graphite is used as a grease additive and as a cast lubricant. It enables the casting quality and the use of the mold for a long time. In addition to these, it is used in many areas such as mold release, lining production, heat resistant paint, conductive surface, charcoal brush, battery production, graphite oxide production, pencil production.
