MOLYBDENUM STUDY: Creston project to cost over US$500 …
Annual production is estimated to be 20 million lb of molybdenum and 12 million lb of copper from a 40,000-t/d processing plant. Direct costs, inclusive of copper byproduct credits would be US$6.57/lb MoEq with contract mining or US$5.74/lb MoEq if Creston does the mining. The study determined a pre-tax NPV at an 8% discount rate of US$465.3 ...

Molybdenum processing
The chemical reduction of pure molybdenum xide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process. The first stage of reduction to MoO2 is done in temperatures ranging from 450-650°C.
Molybdenum
Molybdenum is mined as a principal ore and is also recovered as a byproduct of copper and tungsten mining. The world's production of molybdenum was 250,000 tonnes in 2011, the largest producers being China (94,000 t), the United States (64,000 t), Chile (38,000 t), Peru (18,000 t) and Mexico (12,000 t).
