China owns large amount of molybdenum mainly distributing in Liaoning, Shaanxi, Jilin, Shanxi, Henan, Fujian, Guangdong, Hunan, Sichuan and Jiangxi provinces. The most valuable molybdenum mineral is MoS2, and nearly all molybdenum ore be discovered by the form of MoS2. The content of molybdenum in MoS2 is very low, and after some special processes, molybdenum concentrate comes out with the content of molybdenum up to 45-50%.

 

According to the content of molybdenum, molybdenum concentrates can be divided into the following grades.
