Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.
Graphite is the only nonmetal element that is a good conductor of electricity. Natural graphite is used mostly in what are called refractory applications. Refractory applications are those that involve extremely high heat and therefore demand materials that will not melt or .
Apr 25, 2017· Graphite is a natural form of carbon characterized by its hexagonal crystalline structure. It is extracted using both open pit and underground mining methods.

The richest deposits were discovered and mined out for coal and iron ore. Iron and steel melting necessitated manufacturing of materials that accompany metallurgy processes. One of these materials is graphite. The information about marvelous Siberian graphite ore had been spreading since the late 19 th century. This ore is distinct for its ...
Jul 16, 2018· (viii) Reduction of metallic oxides to metal in the extraction of metals from the ores is based on the position of the metal in the activity series. Answer: The method used to extract a metal from its ore depends on the position of the metal in the reactivity series. (a) Metals higher up in the series need to be extracted using electricity.

6. Environmental Impact and Economics of Metal Ore Extraction and mining–quarrying other minerals. Aspects of this discussion applies to minimising the cost of production of any chemical product. What are the social, economic and environmental impacts of exploiting metal ores (mineral extraction), of using metals and of recycling metals – economic, sociological and environmental issues
The second is more satisfactory, since the extraction is more complete, and also allows the addition of reducing agents to decompose any admixed bismuth oxide or sulphide. In the liquation process the ore is heated in inclined cylindrical retorts, and the molten metal is tapped at the lower end; the residues being removed from the upper end.
It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss. It exhibits the properties of a metal and a nonmetal, which make it suitable for many industrial applications.
What Are the Uses of Graphite? ... Graphite can behave like a metal and conduct electricity but also as a nonmetal that resists high temperatures. Crystalline Structure. Graphite occurs naturally as flakes and veins within rock fractures or as amorphous lumps. The basic crystalline structure of graphite is a flat sheet of strongly bonded carbon ...
Sep 10, 2002· Flake graphite can be found in metamorphic rocks evenly spread through the body of the ore or in concentrated lensshaped pockets. The range of carbon concentrations varies from 5% to 40%. Graphite flake can be found as a lamella or scaly form in specific metamorphic rocks such as limestone, gneisses, and schists.

An ore is a rock in which a valube or useful metal occurs. The more demand a certain rock has the more value it has thus it will be more valuble to be mined. The higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a given amount of the metal.
Oct 17, 2011· Graphite and Diamond). An ore is a type of rock that contains important minerals such as gold ore or diamond ore. Usually the term ''ore'' is reserved to rocks containing economically useful metals ...
Chalcopyrite has been the primary ore of copper since smelting began over five thousand years ago. Some chalcopyrite ores contain significant amounts of zinc substituting for iron. Others contain enough silver or gold that the precious metal content more than pays the costs of mining.
"Synthetic graphite" is made by heating highcarbon materials like petroleum coke and coaltar pitch to temperatures in the range of 2500 to 3000 degrees Celsius. At these high temperatures, all volatile materials and many metals in the feedstock are destroyed or driven off. The graphite that remains links into a sheetlike crystalline structure.
