Sungun Copper Mine
The Sungun copper mine ( ) is located in Varzaqan county, East Azarbaijan, Iran, 75 km north west of the provincial town of Ahar. It is the most important geologic and industrial feature in the area and is the largest open-cast copper mine in Iran and is in the primary stages of extraction. The reserves are estimated to be as much as 995 million tons of copper ore. The ore is processed directly at a concentration plant at the mine. The capacity of the concentration plant is 170,000 tons of copper concentrates, with plans to expand to 300,000 tons. References # Singer, D.A., Berger, V.I., and Moring, B.C.

Ahar
Ahar ( fa, italic=yes, اهر, az, اهر) is a city and capital of Ahar County, East Azerbaijan Province, Iran. According to the 2016 census, Ahar was the fourth most populated city of the province with a population of 100,641 in 20,844 families. Ahar was the capital of Karadag Khanate in 18th and 19th centuries. Situation In the wake of Russo-Persian War (1804–13) Ahar, with 3500 inhabitants, was the only city of Qaradağ. Around the mid 1830s the population was estimated to be from five to six thousand inhabitants in about six hundred houses. By 1956 the population had increased to 19816. At the 2016 census, its population was 100,641, in 20,844 families.

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Concentration Plant
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: '' mass concentration'', ''molar concentration'', ''number concentration'', and '' volume concentration''. The concentration can refer to any kind of chemical mixture, but most frequently refers to solutes and solvents in solutions. The molar (amount) concentration has variants, such as normal concentration and osmotic concentration. Etymology The term concentration comes from the word concentrate, from the French , from con– + center, meaning “to put at the center”. Qualitative description Often in informal, non-technical language, concentration is described in a qualitative way, through the use of adjectives such as "dilute" for solutions of relatively low concentration and "concentrated" for solutions of relatively high concentration. To concentrate a solution, one must add more solute (for example ...

Mining In Iran
Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 per cent to the country's GDP. Add other mining-related industries and this figure increases to just four per cent (2005). Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, exploration difficulties, and government control. The most important mines in Iran include coal, metallic minerals, sand and gravel, chemical minerals and salt. Khorasan has the most operating mines in Iran. Other large deposits which mostly remain underdeveloped are zinc (world's largest), copper (world's ninth largest reserves in 2011, according to the managing director of National Iranian Copper Indus ...
