Geology

The main molybdenum ore is molybdenite (molybdenum disulfide). It is treated by sintering to form molybdenum oxide, and then reduced to metal. The main mining areas are USA, China, Chile and Peru. A certain amount of molybdenum produced as a by-product of tungsten and copper. World production is about 200,000 tons per year.

Extraction of molybdenum ore

Molybdenum is contained in various minerals, but only molybdenite (MoS₂) is suitable for industrial production. Molybdenite can occur as the only mineral in the ore body, but often happen in conjunction with the sulphide minerals of other metals, most often copper. The content of Mo in the ore-rich veins range from 0.01 to 0.25%. Depending on the minerals contained in the ore body, molybdenum mines are grouped in three classes:

• Primary mines, which is purposeful extraction of molybdenite.
• Related development where the commercial viability of the mine requires extraction of both molybdenite and copper-bearing minerals.
• If the ore is close to surface, extraction is conducted in an open way.

In the latter case, the Stripping open to reveal the ore body. If the ore is located deep under the ground, used machinery underground collapse. Here large pieces of ore cut, and subsequently collapse under their own weight. The resulting breed is lifted to the surface and treated.

Overview molybdenum

Molybdenum is a silvery metal with a very high melting point. It is produced and sold as a grey powder, which is then under high pressure pressed and sintered. Used in metallurgy as an alloying addition to the alloy to increase their strength, hardness, resistance to corrosion and wear. Molybdenum is toxic. Molybdenum disulfide is used as lubricating additives. The alternative use of molybdenum catalysts for the oil industry, inks for printed circuit boards, pigments and electrodes.
