Molybdenum does not occur naturally as a free metal, it is found in various oxidation states in minerals. The primary commercial source of molybdenum is molybdenite, although it is also recovered as a byproduct of copper and tungsten mining. Molybdenum was first discovered by Carl Wilhelm in 1778.

The molybdenum atom is part of the molybdenum cofactor in the active site of four enzymes in humans: sulfite oxidase, xanthine oxidase, aldehyde oxidase, and mitochondrial amidoxime reducing component. (More information) Excess molybdenum intake causes fatal copper deficiency diseases in .
In 1951 established the branch of the Zangezur copper-molybdenum plant, Dastakert got the status of an urban-type settlement. During that period the village had nearly 4000 residents. But in 1975 the plant was closed and the population decreased, which became a reason, that in 2017 it .
The Zangezur copper-molybdenum complex possesses large molybdenum reserves that are concentrated in the Kajaran deposit. Besides molybdenum, Armenia has significant deposits of copper and gold; smaller deposits of lead, silver, and zinc; and deposits of industrial minerals, including basalt, diatomite, granite, gypsum, limestone, and perlite.
Forecast metallogenic maps with the scale of 1:50000, as well as structural-geological maps of Kadjaran, Agarak, Dastakert, Lichq coopper-molybdenum mines were created. The group participated in the industrial reserves assessment and calculation of the above mentioned mines.

Dastakert can be only reached by the regional H road that connects the village with Sisian in the north, near the Tolors reservoir. Following the independence of Armenia, Dastakert retained its status as an urban settlement until the administrative reforms of November, when it was turned into a rural settlement as part of the Sisian community.
Dec 21, 2018 · Other copper-molybdenum deposits are found in the Teghut, Hankavan, Agarak, Kapan, Dastakert, and Hankasar mines. Gold. Significant gold deposits are located throughout Armenia in mines such as the Mghart Mine, Meghradzor, Sotk Mine, Sofi Bina, Amulsar Mine, Terterasar, and Bardzradir mines. In other regions, gold is mined as gold oxide or in combination with other minerals such as .
The main molybdenum ore is molybdenite (molybdenum disulfide). It is processed by roasting to form molybdenum oxide, and then reducing to the metal. The main mining areas are in the USA, China, Chile and Peru. Some molybdenum is obtained as a by-product of tungsten and copper production. World production is around 200,000 tonnes per year.
After entering Armenian mining industry in September 2007, GLOBAL METALS started developing Armanis gold-polymetallic and Dastakert copper-molybdenum deposits through two ventures in the mining industry: "Sagamar"CJSC and "Molibdeny Ashxarh" LLC, being managed by GLOBAL METALS (ARM) Limited Company Armenian Branch in Yerevan, Armenia.

Molybdenite is the most important ore of the metal molybdenum. Molybdenite is currently being researched as a possible replacement semiconductor for silicon in transistors in electronic chips. Two polytypes are known: molybdenite-2H (very common) and molybdenite-3R (rare).
[PDF]Molybdenum decreased 0.30 USD/Kg or 1.06% since the beginning of 2019, according to trading on a contract for difference (CFD) that tracks the benchmark market for this commodity. Historically, Molybdenum reached an all time high of 41250 in March of 2010 and a record low of 27.20 in July of 2018. Molybdenum is a silvery metal with the sixth-highest melting point of any element, it can ...
Copper-Molybdenum ores Molybdenite (MoS2) is the predominant economic molybdenum mineral. While naturally very hydrophobic and can effectively be floated with just frother, addition of a hydrocarbon oil extender enhances its recovery.
Dastakert copper-molybdenum deposit is situated in the Sisian region of Syunik marz of RA, on the northern slope of Bargushat mountain range, the south-east parting of Zangezur mountain range; 3 km to the south of Dastakert, 2050-2500m above the sea level.
molybdenum. It is often associated with other sulfideminerals of other metals, most commonly copper. Molybdenum is typically concentrated through selective flotation.The molybdenite is converted into molybdic oxide through roasting in a ple hearth furnace. The roasted molybdenite concentrates are generally known as 'tech-oxide'.
About 400 of these are exploited, including 22 metal mines: Seven copper-molybdenum mines, four copper mines (operated in the southern part of the country in Kadjaran, Dastakert and Agarak), 14 gold mines (operated in Sodq and Meghradzor) and gold-poly-metallic mines, two poly-metallic mines, two iron ore mines, and one aluminum mine.
