The invention discloses a method for efficiently utilizing complex molybdenum ore with wastewater self-circulation, and belongs to the technical field of molybdenum comprehensive recovery. The methodaims at the problems such as large wastewater discharging amount and difficulty in economic and efficient treatment caused by the fact that existing complex molybdenum ore is used for metallurgy directly without being subjected to beneficiation enrichment; combined with the characteristics of wastewater process and through the processes of ball milling pulping, oxygen pressure leaching, ammonium molybdate preparation, raffinate purification and recycling and acid precipitation mother liquor purification and recycling from the angles of classification treatment and quality separation recycling,the molybdenum recovery rate in the complex molybdenum ore is 90% or above, and waste water is fully recycled in a system; and the economic development and utilization of the complex molybdenum ore under the current industria
