Abstract An effective method for comprehensive and high-efficient utilization of low-quality tungsten and molybdenum ore is developed to obtain composite alloy of tungsten and molybdenum. The thermodynamics of reduction reactions of the ores were calculated with different reducing agents: C+SiO2, Si, SiC, and CaC2. The starting temperatures of reduction reactions are 1 552,1 403,1 613 and 2 002 K, respectively. Calcium fluophosphate Ca5(PO4)3F is the most difficult component in the ore to be reduced in the reduction process because of its compact structure and large bond energy. Thus the key to develop high quality composite alloy of tungsten and molybdenum is reducing the content of impurity elements P, F.
