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.


GYPSUM, ANHYDRITE, PLASTERS
Mineral Detail:

MINERALS GYPSUM, ANHYDRITE, PLASTERS Gypsum is a mineral containing calsium sul­ fate in its chemical composition. In addition to natural Gypsum, synthetic gypsum is pro­ duced as well. Important gypsum sources include ankm orum, Yozgat, Erzincan, Ankara-Bala, Sivas, Kars-Kağızman, Tuzluca, Denizli-Sarayköy and Niğde-Karakol.


MAGNESITE
Mineral Name:
Mineral Detail:

MINERALS MAGNESITE Magnesite is a compound of magnesium, its chemical formula is MgC03, and its color varies between white, yellow, grey and brown. It is found in nature as cryptocrystalline and crystalline. It is a tough and complex mineral, and is an alteration product of serpentinite or similar rock types. There are magnesite reserves in Konya, Balıkesir, Bursa, Bilecik, Ankara, Kütahya, Eskişehir and Erzincan.
