Copper and Molybdenum Flotation Process Xinhai
Copper and molybdenum are accompanying minerals. Almost over 20 percent molybdenum is recovered from copper and molybdenum. Copper and molybdenum ore, which are mainly copper ore, is existed as porphyry copper with high recovery value and low grade of molybdenum (~%). Copper in copper and molybdenum is existed mainly as CuFeS2, Cu2S, while molybdenum is existed as MoS2.

Transition metal dinitrogen complex Wikipedia
The oxidation state of molybdenum remains unchanged until the last step when it is oxidized from Mo(III) to Mo(IV). For the rest of the cycle, dinitrogen is bound to Mo via a double or a triple bond accompanied by the change in oxidation state of Mo from +4 to +5 and the release of 2 equivalents of ammonia gas.
