Molybdenum - Wikipedia

Chemical properties. Molybdenum is a transition metal with an electronegativity of 2.16 on the Pauling scale. It does not visibly react with oxygen or water at room temperature. Weak oxidation of molybdenum starts at 300 °C (572 °F); bulk oxidation occurs at temperatures above 600 °C, resulting in molybdenum trioxide.

Molybdenum Processing

Large rotary rakes move the molybdenite concentrate to promote the chemical reaction. Desulfurisation systems such as sulfuric acid plants or lime scrubbers remove sulfur dioxide from the effluent roaster gases. The resulting roasted molybdenite concentrate typically contains a minimum of 57% molybdenum, and less than 0.1% sulfur.

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.
