Molybdenum

MGT Mineral Company as a main producer, supplier and exporter of several minerals and materials in Middle East, is located in Iran. MGT Mineral Company has a lot of experience in exporting and is active in case of Molybdenum supplying. 

Molybdenum is a chemical element with symbol Mo. Molybdenum doesn't occur naturally as a free metal on Earth, however rather in various oxidation states in minerals. Molybdenum is a paragenesis of Copper. The most significant application of Molybdenum is in steel alloys. Alloys that are made by Molybdenum have strategic applications in aviation industries. 

Molybdenum was first discovered as an element in 1778 and first isolated as metal in 1781. It is primarily used to create steel alloys which need to be highly resistant to heat and corrosion. It gains its name from the Greek word for lead, molybdos, as its ores were originally mistaken for lead compounds.

Iran's produced Cathode Copper exceeds 200000 ton in year. Therefore, Iran has a great potential to produce Molybdenum as byproduct of Copper. Major raw materials for production of Molybdenum are separated from Copper with leaching. 

According to the published statistics by United States Geological Survey (USGS), Iran has 2.33 percent of Molybdenum production in 2012. Thus, Iran is one of the best Molybdenum Supplier in the world.

MGT Mineral Company honorably can provide any necessary conditions for Molybdenum Exporting.

What is Molybdenum ore?

The most common mineral of Molybdenum is Molybdenite (Molybdenum disulfide, MoS2). Similar in appearance graphite, Molybdenite has a lubricating effect that is a result of its layered structure. The atomic structure consists of a sheet of Molybdenum atoms sandwiched between two sheets of sulfur atoms. The Mo-S bonds are strong, but the interaction between the sulfur atoms at the top and bottom of separate sandwich-like tri-layers is weak, therefore in easy slippage as well as cleavage planes.

Another normal mineral of Molybdenum is Molybdite. Molybdite is a naturally occurring mineral form of Molybdenum trioxide MoO3. It occurs as yellow to green needles and crystallizes in the orthorhombic crystal system.

Molybdenite Occurrence

Molybdenum only occurs as mineral ore, most commonly Molybdenite (MoS2) but also in Wulfenite (PbMoO4) and Powellite (CaMoO4), and it does not occur as a native metal. Deposits usually occur in high-temperature hydrothermal veins, disseminated porphyry type deposits (with and without associated major copper mineralization), in contact metamorphic deposits in limestone with calcium silicate minerals and in pegmatites, granites, and aplitesii. Ores containing molybdenum often occur alongside those of tin and tungsten and copper. As such Molybdenum is often obtained as a byproduct of mining and processing of these metals.

Most of the times, Molybdenite occurs in high temperature hydrothermal ore deposits. Its associated minerals include pyrite, chalcopyrite, quartz, anhydrite and fluorite. 

Molybdenum never occurs free in nature, instead, it is always component of a compound. In addition to Molybdenite, it also occurs commonly as Wulfenite (PbMoO4). Its abundance in the Earth's crust is estimated about 1 to 1.5 parts per million. That makes it about as common as tungsten and many of the other rare earth (lanthanide) elements. About two-thirds of all the Molybdenum in the world is located in Canada, Chile, China, and the United States. 

 

Economic Classification

Molybdenum is a chemical element that does not occur naturally as a free metal on Earth. We can have Molybdenum with even 99.9% purity, after several leaching steps in Mineral Processing factories.

Molybdenum Usages:

  • Molybdenum is commonly present in alloy steel that used in pipelines and drilling equipment in the oil and gas sector. Its corrosion-resistance is critical for preventing pipeline leaks and for the durability of steel used in the vicinity of seawater. Molybdenum’s high strength and ability to function well in harsh conditions make it ideal for the tough work done by drilling bits and pipe used to reach oil and gas reserves thousands of meters underground.

     Molybdenum has high melting point, therefore, it is produced and sold as a grey powder. Many Molybdenum items are formed by compressing the powder at a very high pressure.

     The addition of Molybdenum to stainless steel leads to corrosion protection and improves its strength. These properties cause it to be a considerable solution for many of the challenges in industry. Stainless grades containing Molybdenum are widely used including in pharmaceutical, pulp and paper and chemical plants, tanker trucks, ocean-going tankers and desalination plants.

    Molybdenum disulfide (Molybdenite) is used as a lubricant additive. Other uses of Molybdenum include catalysts for the petroleum industry, links for circuit boards, Pigments and electrodes.
