Molybdenum | Linus Pauling Institute | Oregon State University

Molybdenum is an essential trace element for virtually all life forms. It functions as a cofactor for a number of enzymes that catalyze important chemical transformations in the global carbon, nitrogen, and sulfur cycles . Thus, molybdenum-dependent enzymes are not only required for human health, but also for the health of our ecosystem. Function

Extraction - molybdenum

The extraction of molybdenum. Molybdenum comes from a sulphide ore called molybdenite. First, the ore must be crushed into a powder and then the copper sulphide must be separated from the rest. What is left is molybdenum sulphide and that is roasted. Now there is molybdenum concentrate and that is then made into molybdenum oxide.
