A sample of molybdenite ore from the Climax mine in Colorado, USA James St. John / Flickr. Only around 90 chemical elements occur in nature. Some of these are very familiar – from lustrous precious metals such as gold and platinum, to the oxygen in the air we breathe and the carbon that forms the backbone of the molecules of life.

1 J.W. Blossom, Molybdenum, from Minerals Yearbook …

Almost all molybdenum is recovered from low-grade deposits of the mineral molybdenite, which is naturally occurring molybdenum disulfide (MoS 2), mined either from a primary deposit, or as a byproduct of copper processing.1 In 1993, one mine extracted molybdenum ore, and nine mines recovered molybdenum as a byproduct. Two plants

Molybdenum Ore Washing

Molybdenite is the only molybdenum ore that separates readily through the floatation process, possibly because of how, as a fine particle, it repels, or is repelled by water molecules. molybdenum disulfide is changed to molybdenum oxide by heating it in air. the sulfur is removed as sulfur dioxide gas.
