Oct 05, 2018· Sri Lankan graphite 90%C+ - Saint Jean Carbon. Sri Lanka is the only region in the world that produces vein (lump) graphite with a carbon content of more than Sri Lanka has been mining graphite for 200 years.
Graphite is one of two naturally occurring crystalline forms of the sixth element, carbon, the other being diamond. It is a soft greyish black mineral with a metallic lustre.
It is found naturally in three different forms: crystalline flake, amorphous and lump or vein graphite, and depending on its form, is used for a number of different applications. As previously touched upon, graphite has a planar, layered structure; each layer being made up of carbon atoms linked together in a hexagonal lattice.

The carbon-carbon bond length in graphene is ~0.142 nm, and these sheets stack to form graphite with an interplanar spacing of 0.335 nm. Graphene is the basic structural element of carbon allotropes such as graphite, charcoal, carbon nanotubes, and fullerenes.
The origin of vein graphite, also known as lump graphite, is particularly special as it is apparently formed by hydrothermal fluids. An outstanding feature of vein graphite is that its deposits reach a graphitic carbon content of above 90%, even purities up to 99.5% are possible.
Feb 12, 2019· Asbury Carbons Inc. mines, processes, supplies, and markets graphite and carbon-based products for use in industrial applications in America and around the world.
Graphite is gray to black in color, opaque with a metallic luster. It is a fairly soft crystalline form of carbon with a Mohs hardness of 1 to 2. Stable and chemically inert at normal temperatures, graphite has a very high sublimation point, in the absence of air. In its pure form, it is odorless, tasteless and nontoxic.
The Asbury Advantage. The world's most reliable source for high-quality graphite, cokes, coals, carbon materials and engineered solutions.
Lump or vein graphite is considered to be one of the rarest commercially valuable natural graphites, and Sri Lanka is the only commercial producer of this highest quality of graphite. Coal, diamond, and graphite are the three allotropic forms in which carbon is found naturally.
Graphite oxide, formerly called graphitic oxide or graphitic acid, is a compound of carbon, oxygen, and hydrogen in variable ratios, obtained by treating graphite with strong oxidizers. The maximally oxidized bulk product is a yellow solid with C:O ratio between 2.1 and 2.9, that retains the layer structure of graphite but with a much larger ...
RS Mines, exploration and extraction of natural, high carbon purity, highly crystalline Sri Lankan vein graphite. Extracting natural crystalline vein graphite from RS Mines' flagship mine, The Queen's Mine, for graphite and graphene value added products.
Home » Graphite: A Multifunctional Additive for Paint and Coatings. Graphite: A Multifunctional Additive for Paint and Coatings. October 1, 2003. ... with some vein graphite actually reaching 99.5% graphitic carbon in the "as-found" state. Vein graphite is mined using conventional shaft or surface methods. Although several small deposits of ...
Vein graphite is a naturally occurring form of pyrolitic carbon (solid carbon deposited from a fluid phase). Vein graphite has a morphology that ranges from flake-like for fine particles, needle or acicular for medium sized particles, and grains or lumps for very coarse particles.
The Signature™ family of graphites and carbon materials, in powder and granular form, includes amorphous graphite, crystalline flake and vein graphites, synthetic (artificial) graphite, along with calcined petroleum cokes.
An outstanding feature of vein graphite is that its deposits reach a graphitic carbon content above 90%, even purities up to 99.5% are possible. Sri Lanka currently is the only country where vein graphite is mined in large quantities.

The chemical symbol for graphite (carbon) is C*indicating that it is composed solely of carbon. In the commercial arena, the words carbon and graphite are often used interchangeably. ... Crystalline Lump (Vein) Graphite Lump graphite deposits are found in fissure fillings in veins, fractures or cavities in either igneous or metamorphic rocks. ...
Graphite in this form is found all over the world, but is only currently mined in Sri Lanka. Of the types of graphite it is considered the rarest. Vein graphite uses. Vein graphite is used in advanced, thermal and high-friction applications such as car brakes and clutches.
Vein graphite (Medium to High Carbon %) Amorphous graphite (Medium to High Carbon %) Flaky graphite (Low Carbon %) About the deposit. Kahatagaha-Kolongaha is the world biggest crystalline graphite mine which contains above 95% pure Carbon. Geologists believe that deposits contain graphite as vein type until 2050ft depth from the surface.
Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

Vein Graphite (also known as Sri Lankan Graphite or Ceylon Graphite) is a naturally occurring form of pyrolitic carbon (solid carbon deposited from a fluid phase). Vein graphite has a morphology that ranges from flake-like for fine particles, needle or acicular for medium sized particles, and grains or lumps for very coarse particles.
As for individual carbon allotropes, graphite is found in large quantities in the United States (mostly in New York and Texas), Russia, ... There are three types of natural graphite—amorphous, flake or crystalline flake, and vein or lump. Amorphous graphite is the lowest quality and most abundant. Contrary to science, in industry "amorphous ...
Vein graphite, also known as lump vein, crystalline vein graphite, Sri Lankan graphite, or Ceylon graphite, is a naturally occurring form of pyrolitic carbon (solid carbon deposited from a fluid phase).
Synthetic graphite is specially manufactured by heating high-quality calcined petroleum cokes and carbons at 2700-3000°C. It is an ideal product for lubricants, ceramics, brake and friction products, cement additives, alloys, paints and coatings, and plastics, among many others.
Graphite deposits result from the metamorphism of sedimentary rocks rich in carbonaceous matter or from precipitation from carbon-bearing fluids (or melts). The latter process forms vein deposits...
