Molybdenum Ore Reserves IMOA
A number of molybdenum-bearing minerals have been identified, but the only one of commercial significance is molybdenite (MoS 2) a natural molybdenum sulfide. In ore bodies, molybdenite is generally present in quantities from 0.01-0.25% and is often associated with the sulfide minerals of other metals, notably copper.

IMOA: International Molybdenum Association
The International Molybdenum Association (IMOA) was founded in 1989 and is registered under Belgian law as a non-profit trade association (ASBL) with scientific purposes. We currently represent around 95% of mine production and almost all conversion capacity outside China. We also represent some mining and conversion capacity within China.
Molybdenum Uses: First Use of Molybdenum,
The chart above refers to molybdenum produced from mined ore, not to scrap material recycled by chemical processes or remelting; hence the name "new molybdenum". About 23% of this material is used to make molybdenum grade stainless steel, while constructional steel, tool and high speed steel and cast iron, taken together use an additional 56%.

Molybdenum processing, preparation of the ore for use in various products.. Molybdenum (Mo) is a white platinum-like metal with a melting point of 2,610 °C (4,730 °F). In its pure state, it is tough and ductile and is characterized by moderate hardness, high thermal conductivity, high resistance to corrosion, and a low expansion coefficient
2012-6-6 · Its main ore mineral is molybdenite, but it is also produced as a by-product from the processing of copper (Cu) ores. It is used mainly for making alloys and stainless steels. It is essential for plants and deficiencies can occur in brassicas, legumes, wheat, sunflowers and some other crops in many parts of the world, mainly on acid and sandy
Molybdenum: resource distribution and production
In nature, molybdenum does not occur as a free metal, but rather in various oxidation states in minerals which contain 0.01%-0.25% molybdenum. Among these minerals, molybdenite is the only one that is suitable for industrial production. According to USGS, in 2013, world molybdenum resources were about 11,000,000 metric tonnes, and molybdenum mine production was
