 · Molybdenum (element #42, symbol Mo) is a metallic, lead-gray element, with a high melting point (4,730 degrees Fahrenheit). This is 2,000 degrees higher than the melting point of steel, and 1,000 degrees higher than the melting temperature of most rocks. Molybdenum …

Molybdenum does not occur naturally as a free metal, it is found in various oxidation states in minerals. The primary commercial source of molybdenum is molybdenite, although it is also recovered as a byproduct of copper and tungsten mining. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead.

MOLYBDENUM. Molybdenum (often referred to as "Moly") is an important metal in both the industrial world and our daily lives. It was found to be a distinct element by Carl Wilhelm Scheele in 1778 but retained its name from the Greek word ''molybdos'' or lead-like. In its pure state, molybdenum is a lustrous grey metal, somewhat heavier ...

Molybdenum metal production. Molybdenum metal is produced by hydrogen reduction of pure molybdic oxide or ammonium molybdate. The chemical reduction of pure molybdenum trioxide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process.
