Molybdenum history

Molybdenum history. In ancient times a number of substances were collectively known by the Greek word 'molybdos,' meaning lead-like. Molybdenite (MoS 2), the most abundant molybdenum-containing mineral, was in this class along with lead, galena, graphite and others.Though they did not distinguish between these various compounds, the ancients certainly used molybdenite.
