Molybdenite: The mineral molybdenite information and pictures

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.
