Molybdenum - Wikipedia

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of ...

The Metal Profile for Molybdenum

Jan 19, 2020  Molybdenum produced as a by-product of copper from copper porphyry deposits, like the Bingham Canyon deposit in Utah, is removed as molybdenum disulfate during flotation of the powder copper ore. The concentrate is roasted to make molybdic oxide, which can be put through the same sublimation process to produce molybdenum metal.
