Although molybdenum is fairly abundant and is found in a number of minerals, its commercial production is primarily from mineral molybdenite, MoS2.


The process involves

  • Roasting the ore - to give molybdenum oxide.
  • This is extracted from the ore using aqueous ammonia, whence it forms ammonium molybdate.
  • Ammonium molybdate is then converted to ammonium dimolybdate which can be isolated as a solid.
  • Heating this gives molybdenum trioxide, MoO3.
  • Finally, the metal is produced by reduction using hydrogen.
