The invention discloses a combined collecting agent for improving the molybdenum recovery rate of low-copper high-molybdenum ore and an application process of the combined collecting agent. The combined collecting agent is prepared from the following raw materials in parts by weight: 2-5 parts of fractionation-grade kerosene higher than 220 DEG C, 1-2 parts of heavy wax, 2-3 parts of motor oil, 1-2 parts of tricyclic aromatic hydrocarbon, and 1-3 parts of v fatty acid polyglycolate serving as an emulsifier. The process is simple, high in applicability, low in production cost, high in molybdenum recovery rate and easy to industrially popularize. A novel combined collecting agent which is good in stability, high in viscosity, capable of easily adsorbing coarse-particle ore and high in collecting capacity and has a certain number of large-molecule aromatic hydrocarbon is synthesized after emulsifying is conducted through the emulsifier, and the recovery rate of molybdenum in the low-copper high-molybdenum ore ca
