molybdenum ore processing method

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: MoO 3 + 2 NH 3 + H 2 O → (NH 4) 2 (MoO 4)
