      FIGURE 1. Locations of Six Molybdenum-Related Ore Deposits Discussed Here, in British Columbia, Canada. Introduction Although molybdenum and molybdenum-copper deposits can be thought of as variations on copper-molybdenum and copper deposits, the limited information on environmental geochemistry does not support this. Molybdenum is a rare element occurring chiefly as the sulphide, rarely wulfenite or powellite may serve as an ore. Molybdenum does not occur in a free state in nature, but may be prepared from its sulfide (molybdenite) direct in the electric furnace, or by the reduction of its oxide by means of carbon, or by the Thermite process.

      (Latin, Molybdaenum), Mo, a chemical element in Group VI of the Mendeleev periodic number, 42; atomic mass, A light gray refractory metal. In nature, molybdenum is represented by seven stable isotopes with mass numb 94–98, and , of which 98 Mo is the most common ( percent). Until the 18th century, the principal .   The primary production is from either Molybdenum porphyry deposits or as a byproduct of copper porphyry deposits. From to the Molybdenum market was characterized by extreme volatility with prices rising from under $5 per pound to over $45 per pound and then dropping to $9 a pound in

In Canada, molybdenum is produced in BC where there is one primary molybdenum mine and several copper mines where molybdenum is produced as a by-product. Canada is the fourth-largest producer of molybdenum in the world, behind the US, China and Chile.

Canada produces close to 7 million kg of molybdenum annually. Molybdenum exploration in Canada is heating up along with demand for the metal. Miners are looking to take advantage of China’s appetite for steel, for which moly is a vital ingredient. Molybdenum (Mo) is a refractory metallic element used principally as an alloying agent in steel, cast iron, and superalloys to enhance hardenability, strength, toughness, and wear and corrosion resistance.

To achieve desired metallurgical properties, molybdenum, primarily in the form of molybdic oxide or ferromolybdenum, is frequently used in combination with or added to. Molybdenum grades are reported for about half of the porphyry copper deposits in Singer et al.

(), range from less than to % Mo, and average about % Mo. Molybdenite is the only molybdenum mineral of significance and is reported in about 70% of the deposits in Singer et al.

Giant porphyry molybdenum deposits are best exemplified by the Climax and Henderson deposits in Colorado. The high grades of these deposits are probably inherited from magmatic molybdenum concentrations of about 4 to 5 ppm, which are high for metaluminous rhyolitic magmas that average about 2 ppm Size: 1MB.

Molybdenum in British Columbia B.C. Molybdenum Deposits The British Columbia Geological Survey’s MINFILE database lists 1, molybdenum-bearing occurrences, of which list molybdenum as the primary commodity.

Mo and Cu-Mo porphyries are the main deposit types. The developed Mo porphyries in B.C. are classified as low-fluorine type, distinct. Abstract. In the study of molybdenum deposits and most other minerals deposits, including copper, lead and zinc, there is speculation that most undiscovered ore results from an increase (or “growth”) in the estimated size of a known deposit due to factors such as exploitation and advances in mining and exploration technology, rather than in discovering wholly new Cited by: 1.

Molybdenum Ores natural mineral formations containing molybdenum in quantities that make its extraction economically feasible.

The reserves of molybdenum in ores in developed deposits range from a few thousand tons to millions of tons. The average molybdenum content in the ores of large deposits ranges from to percent, and in small deposits.

Molybdenum prices are quoted in US$/lb of MoO3. Molybdenum occurs in very low grade percentages, typically ranging from % to %. In the geological world, a grade of % and up is often considered to be high grade.
