Copper

Introduction of company

Copper is a metal which has been used for many years. 85-90% of copper consumed in the World is achieved by extracting from copper mines. Metals are extracted from ore in two ways: Pyrometallurgy and hydrometallurgy. Pyrometallurgy has been used by the humankind ever since the beginning of the human history. Nowadays, more than 95% of metals are procured in this way. Although pyrometallurgical methods have been prevalent, however, during the recent years, new hydrometallurgical methods have been considered, and there was a considerable growth in the production of copper and other basic metals in this way. According to the latest evaluation made in 1997, mineral deposits of copper have been estimated at 57000 million tons all over the World (except China and ex-Soviet), and the mineral copper deposit of Iran is roughly 1900 million tons containing 14 million tons copper, being around 3% of mineral copper deposits of the World. According to studies made, in terms of mineral copper deposits, Iran is located on the World belt of this metal, stretching in direction of the North West – South East axis of the country.

History of copper in Iran

Copper objects and alloys obtained at various points of Iran as well as remains of old primitive furnaces of melting copper show that the old Iranians knew the industry of extracting and melting. Archeological explorations show that mines were fairly prosperous in Iran after the 5th millennium BC. Bronze, golden and silver objects obtained from the next millennium illustrate progresses made in operating mines and metallurgy in Iran. After appearance of Islam particularly during Seljukian (6th century A.H.) and Safavids (11th century A.H.), there was much prosperity in operating mines and metallurgy in Iran.

National Iranian Copper Industries Co.

On July 03, 1972, Kerman Sarcheshmeh Copper Mines Co. (P.J.S.) was incorporated and in 1976 it was renamed National Iranian Copper Industries Co., which encompasses all operations of copper mines in the country. The functions of this company include among others: To extract and operate mines of copper; to produce high grade products of ore and copper products such as cathode, slab, billet, and 8-mm wires. Among the most important copper mines of the country one may name: Sarcheshmeh and Miduk in Kerman, and Songon in East Azerbaijan.

 

 

 

 

 

Aluminium:

Aluminium is a silvery-white metal, the 13 element in the periodic table. One surprising fact about aluminium is that it’s the most widespread metal on Earth, making up more than 8% of the Earth’s core mass. It’s also the third most common chemical element on our planet after oxygen and silicon.

At the same time, because it easily binds with other elements, pure aluminium does not occur in nature. This is the reason that people learned about it relatively recently. Formally aluminium was produced for the first time in 1824 and it took people another fifty years to learn to produce it on an industrial scale.

The most common form of aluminium found in nature is aluminium sulphates. These are minerals that combine two sulphuric acids: one based on an alkaline metal (lithium, sodium, potassium rubidium or caesium) and one based on a metal from the third group of the periodic table, primarily aluminium.

Aluminium sulphates are used to this day to clean water, for cooking, in medicine, in cosmetology, in the chemical industry and in other sectors. By the way, aluminium got its name from aluminium sulphates which in Latin were called alumen.
