Molybdenum - Wikipedia

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, from 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 other metals ...

Extraction - molybdenum

The extraction of molybdenum. Molybdenum comes from a sulphide ore called molybdenite. First, the ore must be crushed into a powder and then the copper sulphide must be separated from the rest. What is left is molybdenum sulphide and that is roasted. Now there is molybdenum concentrate and that is then made into molybdenum oxide.
