Uranium and molybdenum recovery from copper leaching

For Molybdenum, the most common method used to obtain it is in the molybdenum trioxide form, MoO 3, through the flotation of sulfide molybdenum minerals, in this case, molybdenite, MoS 2, which is commonly present with chalcopyrite, CuFeS 2. The molybdenite is finally roasted and turned into MoO 3.

Molybdenum: isolation. Isolation: it is not normally necessary to make samples of molybdenum metal in the laboratory since it is readily available commercially. Industrially, its extraction is sometimes linked to copper production. The normal process is for the sulphide MoS 2 to be "roasted" to form the oxide MoO 3. This is often used directly in the steel industry.
