MINERALS OF COMPANY


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.


MINERAL OILS
Mineral Name:
Mineral Detail:

MINERALS MINERAL OILS Fossil fuel or mineral fuel, hydrocarbon and natural energy source containing high levels of carbon. Coal, oil and natural gas; is a prime example of such fuels. It is formed by the dissolution of dead living organisms in an oxygen-free environment for millions of years.


BENTONITE
Mineral Name:
Mineral Detail:

MINERALS BENTONITE is an absorbent aluminium phyllosilicate, essentially impure clay consisting mostly of montmorillonite. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.


PERLITE
Mineral Name:
Mineral Detail:

MINERALS PERLITE Is used in a number of different situations. The majority of perlite is used in construction products, mainly ceiling tiles and roof insulation products, but also as refractory bricks (a refractory brick is a brick designed to withstand very high temperatures), pipe insulation, and filling in masonry block construction. For example, loose perlite is poured into holes in concrete blocks after they are laid in place to improve the insulating quality of the construction. Perlite is also used as an insulator in other ways in the construction of buildings. It reduces noise and, since it is non-combustible, it also improves the fire resistance of different construction components in buildings.


OTHER MINERAL SUBSTANCES
Mineral Name:
Mineral Detail:

MINERALS OTHER MINERAL SUBSTANCES VERMICULITE, SEPIOLITE, ARSENIC SULFUR, ZIRCONIUM SILICATE


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.


UNROASTED IRON PYRITES
Mineral Name:
Mineral Detail:

MINERALS UNROASTED IRON PYRITES Pyrite is an iron sulfide mineral and one of the most ubiquitous minerals of earth's crust. It is found in igneous, metamorphic and sedimentary rocks and crystallizes at both high and low temperatures. Its yellow color and metallic luster occasionally fool inexperienced people who confuse it with gold - hence the name "fools gold". The uses of pyrite are declining. The main uses today are the production of sulfur dioxide for the paper industry and sulfuric acid for the chemical industry. Other sources of these substances are replacing what was once produced from pyrite. It is rarely mined for its iron content because the associated sulfur contaminates the iron to render it brittle and useless for most applications.
