MINERALS OF COMPANY


NATURAL GRAPHITE
Mineral Name:
Mineral Detail:

MINERALS NATURAL GRAPHITE Graphite is rather common, but fine crystals are rare. Most Graphite mining areas produce enormous quantities from a single or several large Graphite veins. Graphite has the same chemical composition as the mineral Diamond, but the atomic structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties. Much care should be given to Graphite specimens, especially thin crystals, which are fragile. It is very hard to wash crystals as they peel off and get ruined. Graphite will also smudge on its surface, and can get worn out if it is moved around too much. Graphite also smudges the hand if handled, and will smudge a paper or cardboard box if it is stored in one. The "lead" in pencils is in fact composed of a mixture of Graphite and clay. There is no lead in pencils at all. Much of the commercially mined Graphite is used for pencil fillings. Its main function, however, is as a lubricant. It has many electrical uses, primarily because it is the only common nonmetal that is a good conductor of electricity.


FERRO CHROMIUM
Mineral Name:
Mineral Detail:

MINERALS FERRO CHROMIUM Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The ferrochrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China. The production of steel is the largest consumer of ferrochrome, especially the production of stainless steel with chromium content of 10 to 20% is the main application of ferrochrome.
