Graphite come from carbon.
GRAPHITE is a form of elemental carbon. It is one of the three allotropic forms which the element carbon exists in nature, the other two being coal and diamond. It crystallises in hexagonal system in platy form but it is rare that perfect crystals of graphite have been found.  Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. In milling, the incoming graphite products and concentrates can be ground before being classified (sized or screened), with the coarser flake size fractions (below 8 mesh, 8–20 mesh, 20–50 mesh) carefully preserved, and then the carbon contents are determined. The graphite scrap comes from pieces of unusable electrode material (in the manufacturing stage or after use) and lathe turnings, usually after crushing and sizing. Most synthetic graphite powder goes to carbon raising in steel (competing with natural graphite), with some used in batteries and brake linings.

The most common use of graphite, as a great deal of schoolchildren know, is as lead in pencils. Pencil lead is made from the slag (the not so fine crystals of graphite) mixed with clay. However, the finer crystals of graphite are often sought after and used in electrical components, as graphite is one of the only conductors of electricity that is not metallic in origin. Though graphite is chemically similar to diamond, its physical qualities are very different. Graphite is usually found in brittle, inflexible flakes; graphite is dark and greasy to the touch, smudging readily on objects. There are a variety of sites where graphite (both in its fine and less fine states) is found: Pargas, Finland; Naples, Italy; and the Francon Quarry near Quebec are all graphite-rich places.

Description: Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all forms of carbon-based life, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen. Moreover, it has an affinity for bonding with other small atoms, including other carbon atoms, and is capable of forming multiple stable covalent bonds with such atoms. As a result, carbon is known to form almost ten million different compounds; the large majority of all chemical compounds. So, for the next time your mind gets to wandering, here’s the answer: Pencil lead does not come from lead. In fact, even though it’s greasy and black and soft like lead, it is actually a carbon material called graphite. Graphite is mined as flakes or lumps and ground together with clay, then baked into the little sticks you see encased in wood or inside mechanical pencils. But, in 1779, chemist Carl Scheele made the discovery that it was a form of carbon and unrelated to lead. The word graphite came from the Greek verb graphein, which means, “to write.” Still, people continued to refer to it as lead. At first, the Borrowdale deposit was the main source of pencil lead throughout Europe. Carbon (from Latin: carbo coal) is a chemical element with symbol C and atomic number 6. On the Periodic table, it is the first (row 2) of six elements in column (group) 14, which have in common the composition of their outer electron shell. Moreover, it has an affinity for bonding with other small atoms, including other carbon atoms, and is capable of forming multiple stable covalent bonds with such atoms. As a result, carbon is known to form almost ten million different compounds; the large majority of all chemical compounds.
