metallurgical process of copper molybdenum

Review Molybdenum Recovery from Mineral Raw Materials by ...

Molybdenum (sulfide and oxidized), coppermolybdenum and uranium ores as well as secondary raw materials are the sources for molybdenum production. In, the pyrometallurgical methods (Zelikman, 1970) were used for molybdenum breakdown from sulfide ores and concentrates. These methods are environmental dangerous and do not allow to .
