Abstract: China's shortage of molybdenum ore resource is an undoubted fact. In the case of increasing decrease of easily-benefication sulphide-molybdenum,To rationally exploit and utilize complex refractory molybdenum ore resource is of great importance to the relaxation of the contradiction between the supply and demand of molybdenum ore and the security of the nonferrous metal minerals industrial economy. This paper reviews the progress in China's benefication technology and the resources situation for complex refractory molybdenum ores. Meanwhile, in light of their property features, the orientation of further research is pointed out.
