2. Molybdenum ores
The main molybdenum-bearing minerals are molybdenite (MoS 2 ), wulfenite (PbMoO 4 ), molybdite (FeO 3 , 3MoO 3 + H 2 O), powellite [Ca(Mo, W) O 4 ] and a few other ores that are of no economic interest. Molybdenite is the most widespread mineral, followed by wulfenite; powellite exists only in small quantities, and is sometimes associated with scheelite (CaWO 4 ). Currently, only molybdenite is mined; in the past, wulfenite has contributed to substantial molybdenum production. Molybdenum is separated from scheelite ores containing powellite during the preparation of tungstic...

Price
The price of molybdenum powder in 1992 was in the region of $15 to $20; manufacturing difficulties and the cost of milling considerably increase the price of rolled semi-finished products as the diameter or thickness decreases (figure
