Mineral Processing 101 : Molybdenum Ore Beneficiation
2020-12-22 The beneficiation processing of molybdenum ore is mainly performed by flotation, and the recovered molybdenum mineral is molybdenite (MoS2). Sometimes in order to improve the quality of molybdenum concentrate and remove impurities, the concentrated molybdenite would be subjected to a further step of chemical beneficiation processing.

Molybdenum: mining and processing-Metalpedia
Metallic molybdenum is produced by hydrogen reduction of pure molybdenum trioxide (MoO3) or ammonium dimolybdate (ADM). The production is carried out in electrically heated tubes or muffle furnaces, into which hydrogen gas is introduced as a countercurrent against the feed.
How Is Molybdenum Mined and Processed? Refractory
Molybdenum exists in many minerals, but only molybdenite (MoS2) is suitable for the industrial production of molybdenum products. Molybdenite may be the only mineralized mineral in a single ore body, but it usually co-exists with other metals, especially copper sulfide minerals. The molybdenum content of each ore body is between 0.01 and 0.25%.
