Molybdenum - Wikipedia

In molybdenite processing, the ore is first roasted in air at a temperature of 700 °C (1,292 °F). The process gives gaseous sulfur dioxide and the molybdenum(VI) oxide: 2 MoS 2 + 7 O 2 → 2 MoO 3 + 4 SO 2. The oxidized ore is then usually extracted with aqueous ammonia to give ammonium molybdate:

Flotation separation of molybdenite from talc using a new ...

In the flotation of sulfide minerals, the separation of molybdenite and talc is a difficult problem. Talc is the main gangue mineral of molybdenite, it has good natural hydrophobicity and a similar layered structure as molybdenite, so inhibitors are often used to separate them. But the reverse flotation method is often used to inhibit molybdenite, and the separation effect is not satisfactory.
