Discovery of Molybdenum. Molybdenite, also known as molybdena, is a soft black mineral that was once used to make pencils. The mineral was often confused for graphite and it was thought to contain lead.It is now known to be molybdenum disulfide (MoS 2).. In 1778 Swedish scientist Carl W. Scheele proved that molybdenite was not graphite nor did it contain lead.
