Examples from the Web for molybdenite
The larger part of the world's production is from the molybdenite ores.
The chief ore minerals are molybdenite (molybdenum sulphide) and wulfenite (lead molybdate).
In molybdenite deposits secondary concentration has not been important.
Wulfenite is rather common in the upper oxidized zone of deposits which contain lead minerals and molybdenite.
In the deposits of New South Wales they are found associated with molybdenite in quartz gangue, in pipe-like deposits in granite.
- a soft grey mineral consisting of molybdenum sulphide in hexagonal crystalline form with rhenium as an impurity: the main source of molybdenum and rhenium. Formula: MoS 2
