Rhenium, molybdenum and tungsten are the elements demanded by high-end technologies. These metals are found in process solutions in forms of their oxyanions: ReO 4-, MoO 4 2- and WO 4 2-. The latter two can exist in forms of iso- and/or heteropolyanions. Basically, all three metals demonstrate very similar chemical behavior in aqueous solutions.

Molybdenum | Mo - PubChem

Molybdenum is a chemical element with the symbol Mo. Pure molybdenum exists as a dark-gray or black powder with a metallic luster or as a silvery-white mass. It does not occur naturally in the pure metallic form. It is principally found as oxide or sulfide compounds. Therefore, almost all exposure is to a molybdenum compound rather than the actual metal alone.
