MOLYBDENITE (Molybdenum Sulfide)

Molybdenite is a very soft metallic mineral. It can be easily confused with graphite, but not with many other minerals. Graphite has a darker black-silver color and a black-gray to brown-gray streak, whereas molybdenite has a bluish-silver color and streak. Unfortunately, the difference is so slight that it is recommended that the two minerals be seen side by side.

Molybdenite is the most prevalent molybdenum-bearing mineral, and is named after that element. Prior to the discovery of molybdenum as a separate element in 1778 by Karl Wilhelm Scheele, Molybdenite was thought to be Graphite or a lead ore.In fact, the word molybdos means "lead" in ancient Greek. Molybdenite forms in two distinct crystal polytypes: Molybdenite-2H and Molybdenite-3R.
