Molybdenum, which belongs to hexagonal crystal system, is a metallic element with lead gray color and metallic luster. Its proportion is from 4.7 to 4.8, hardness 1 to 1.5 and melting point 795 ℃. MoS2 is easily oxidized to MoS3 when it is heated to 400 ~ 500 ℃. Nitric acid and aqua regia can contribute to the resolution of molybdenite (MoS2). Molybdenum has advantages such as high strength, high melting point, corrosion resistant, and abrasion resistant. So it has been widely used in industry.

Molybdenum ore processing plant or molybdenum ore beneficiation plant is made up of molybdenum beneficiation, copper molybdenum beneficiation, tungsten molybdenum beneficiation, molybdenum bismuth beneficiation and molybdenum concentrate. Main equipment of Molybdenum processing plant includes feeder, jaw crusher, ball mill, spiral separator, mine mixing barrel, flotation machine, concentrator, dryer and other auxiliary equipment.

Sodium sulfide and sodium cyanide methods are commonly used to separate molybdenum and cooper. The beneficiation times of molybdenum primarily depend on its total enrichment ratio, if the total concentration ratio is high, there will be more beneficiation times; on the contrary, low enrichment ratio is leads to less beneficiation times.
